Welcome to MAYAN SACRED SCIENCE
Introduction
In the culture of the Maya, especially during the height of their Classic Period (300 A.D. – 900 A.D.), what we now know as their disciplines of religion, philosophy, prophecy, Astronomy and science seemed to be viewed and practiced by them in a holistic manner. Each discipline supported the other and no one discipline was asserted without the help and approval of the others. Their astronomical observances, being sensitive to the true cyclical nature of the heavens, provided the information to develop explanations for creation, religious ritual, philosophy of life and living, and everyday practice in real life. All seemed to blend together into a rather holistic worldview and societal reality.
Unfortunately, the framework and biases of todayπs western thinking does not offer a container that can hold Mayan cosmic understanding. Especially compared with the Maya,western science is a profane science because it is concerned only with the material things of a three-dimensional reality and denies (for all practical purposes) the supra-sensory spiritual realms or the ≥supernatural≤. The handmaiden of profane science is the profane intellect, which can analyze data and makes Aristotelian arguments for anything as it attempts to contain all truth within the ≥natural≤ universe.
The Calendars
The Maya had some seventeen different calendars. Many track back ten million years and even today are extremely difficult to understand. They utilized this understanding of the universe to determine the best ≥times≤ for all things. This article will concentrate on four of the most important calendars and an amazing understanding of a future time of cosmic completion.
Haab ≠ based on the cycles of the earth around the sun. It has 360 + 5 days totaling 365. It has 18 months with 20 days in each month (18*20= 360). The
19th month called Vayeb had 5 days. These last five days were considered extremely unlucky. Finally decoded in 1987, Jose Arguelles identified July 26th as the Haab new year.
Tun-Uc – Is the moon calendar. It is based on 28 days and is broken down into 4 smaller cycles of 7 days each (these are the 4 phases of the moon).
Tzolkin ≠ is the sacred calendar used for cerimonial and ritual events and is based on the movement of the constellation ≥Pleiades≤. The Pleiades were seen as the tail of a rattlesnake called, “Tz’ab.” The sunπs revolution around the Pleiades cycle is 25,770 years. Yet, it is reflected in the calendar as a cycle of 260 days (which is the product of 13 and 20). 13,18 and 20 are the sacred Maya numbers. The beginning of this count is on August 13th 1359 B.C.(Gregorian Date) or August 26th 1358 (Julian). This date was Each day was named with one of 20 day names plus a number that cycled from 1 to 13. 260 days equals 9 months, the gestation period for a human being. ≥Ahau Katun≤. The Tzolkin calendar needs adjustment only 1 day every 380,000 years. Compared to our Gregorian mess ≠ this is amazing.
Even as early as 800 B.C. and, more likely as early as 1000 B.C. — these Mesoamericans had realized that they could calibrate the beginning date of
their sacred almanac (August 13) anywhere within their homeland, even though the original fixing of that event took place only with the zenithal passage of the sun over Izapa in the far south of Mexico. This could be done simply by counting 52 days following the summer solstice and marking the
position of the setting sun against the horizon. They employed constructed artifacts (such as pyramids or the alignment of streets) in such locations to mark the resulting azimuths. It is these alignments which occur throughout the Mesoamerican cultural realm and whose average azimuth measures 285.5∫.
On that one special day in 1359 B.C., ther was a heliacal rising of the planet Venus (at 2:48 a.m.) over the volcano Tajumulco, the highest mountain in all of Central America.
The Tzolkin can be regarded as a periodic table of Galactic frequencies, because it is a fractal of the vague count of the 25,770-year precession of the equinoxes. The 25,770 -year periodicity of extinctions reported in extensive literature is related to comet showers, and possible pole shift.
The Tun or ≥Long Count≤ ≠ used to identify past and future events. It describes changes in the perception of human consciousness. It was developed 500 years after the Tzolkin and is said to harmonize with it using a 13:20 relationship. The long count is actually a modified base 20 number system: All periods except the Tun are 20 times the previous period. The Tun recorded accumulated years of 360 days consisting of 18 months each having 20 days.
The Maya used placeholding arithmetic and were the first known people in history to use the concept of zero. There are 13 lunar cycles in a year and 20 amino acids in the DNA. 13 * 20 =260, which is the exact number of different cells in the human body. It is believed that knowledge about the Long Count however was given to the Maya by a pre-classical people the ≥Epi-Olmec≤. The Maya brilliantly refined it. The Tun was typically used on stone markers that would commemorate certain events. The date is counted from time zero, the Tun beginning. Like the Jewish calendar, both the Olmecs and the Maya reckoned the beginning and end of their days from sunset.
Mayan ABCπs
These are the Mayan words for periods of time:
Day = Kin (keen)
Month of 20 days = Uinal (wee nal)
Year of 360 days = Tun (toon) = aprrox. 1 year
20 Tuns = K’atun (k’ ah toon) or 7200 days
20 K’atuns = Bπaktun (bock toon) or 144,000 days
Using modern notation, the Tun/Long Count is expressed simply by numbers. For instance, Monday, Jan. 1, 1996 was 1,865,799 days after the starting date, or 12 bak’tun, 19 k’atun, 2 tun, 13 winal, and 19 k’in. This would be written as 12.19.2.13.19. The Long Count was kind of like setting the year. Repeating day cycles akin to our day of week or month is specified in the Tzolkin.
The Calendar Round ≠ is the Tzolkin and the Haab mesh together! for a kind of cosmic gear clock. ≥Portal days≤ in the Tzolkin create a double helix pattern using 52 days and the mathematics of 28. With this combination, Maya were able to track and interpret sunspot events. A calendar round date usually follows a long count in most inscriptions. For example:
A typical Mayan date looks like this: 12.18.16.2.6, 3 Cimi 4 Zotz.
12.18.16.2.6 is the Long Count date.
3 Cimi is the Tzolk’in date.
4 Zotz is the Haab date.
The Books of Knowledge
All but 5 Maya books of knowledge or codices were completely destroyed by the conquistadors. So much knowledge has been lost. The remaining Maya codices are named by the European city in which they are kept. Parisian, Madrid, Grolier, Prague and Dresden Codex. The famous Dresden Codex is one of these surviving books and is the only one to contain ≥Long Counts≤.
Information in the Maya codices is formatted in one of two waysãwhat epigraphers call tables and almanacs. The two may be distinguished in that tables contain dates in the Long Count calendar, whereas almanacs generally only record Tzolk’in dates. The Madrid Codex is composed entirely of almanacs, meaning that there are no Long Count dates in the manuscript that allow it to be placed in absolute time.
Yet, in 1992, the University of Guatemala were finally able to correlated the Gregorian and Maya Calendars by identifying a common astronomical event: ≠ the eclipse of July 11, 1991 and the Dresden Codex. This event was predicted by the Maya in the year 755 A.D although it was off by .11 days per event or1 day every 300 years.
This correlation between the Gregorian and ≥Tun≤ Mayan dating system that is generally accepted is called the GMT-correlation (Goodman-Martinez-Hernandez), under the leadership of Eric J. Thompson ≠ [584,285***].
Using the GMT correlation, Harvey and Victoria Bricker have shown that all Dresden Codex predicted 77 solar eclipses (including many not visible in the Yucatan) in the 33 year run of the table from 755 AD that occurred close to warning stations. One of the clearest correlations between a solar eclipse and a Maya calendrical stone inscription or stela is that recorded on Stela 3 found at Santa Elena Poco Uinic in Chiapas, Mexico. Bearing a Long Count date of 9.17.19.13.16. 5 Cib 14 Chen, which is Maya day # 1425516, this inscription most likely records the total solar eclipse whose path of centrality passed directly over this location at 12:48 P.M. local time — having occurred on July 16, 790 (Julian day # 2009802).
This established the beginning of ≥The Long Count≤ and thus the beginning of of a cycle which lasts for 5,125.36 years as starting from dawn on Wednesday Aug. 13th – 3113 or 3114 B.C (0.0.0.0.0). It ends on Dec 21st 2012 A.D (13.0.0.0.0). 5125.36 years = 13 Bπaktuns.
The Precession of the Equinoxes
The ≥Great Cycle≤ is an actual astronomical event called the ≥The Precession of Equinox≤. It will take the Earth 25,770 years to complete and go a ≥full 360≤ around . Each 5,125.40 cycle equals 13 Bπaktuns of 144,000 days each. Each cycle of 13 Bπaktuns was reckoned as an Age or ≥Great Cycle≤. The evolution of each sub phase is presented in details (see Figure 1). Each sub phase last about 20 years.
The Mayas believed that at the end of the great cycle man man crossed the “Galactic Beam” or what we now call the galactic plane. At this point the solar system will experience a fundamental change. They named this change the “Galactic Synchronization”.
The Last Bπaktun
The last Bπaktun began on September 20th 1618 (12.0.0.0.0). From the figure above, we can see that during the period from 1992 up to 2012 (13.0.0.0.0.), our earth has entered the last period of the last phase of the “Great Cycle”.
The Mayas believed this to be a very important period before the “Galactic Synchronization” -they named it the “Earth Regeneration Period”. During this period, the Earth will achieve a complete “Earth Purification”. We are now in a transition period called the ‘Cycle of the merge of the dark and the light.’ During this time humanity is going through great transition. This is a cycle of an increased frequency of change. This is also the age of needed purification.
Additionly, after the Earth regeneration period, the Earth will go beyond the boundary of the Galactic beam and enter the new phase in “Galactic Synchronization”.
Other Maya Dates
Judging by archaeological evidence, 3114 B.C. corresponds exactly to the emergence of the Maya civilization! Remember, the ≥start date≤ is a factor of the ≥Tun≤ calendar which was developed at least 500 years after other Mayan calendars. Somehow The Mayas very existence is intertwined with the cosmic clocks.
In 1992 the Mayan calendar was the beginning of the final and last of the 13th phase in the calendar. Interestingly, there are Christians that believe that the Church as undergone a ≥radical shift in doctrine, purpose and function≤ , a ≥paradigm shift≤ in 1992. http://www.forerunner.com/forerunner/X0520_Ziegler_-_Paradigm_S.html
Cortez landed on good Friday, this day was the first day of a new 52 year cycle and was given special importance by the Maya. Unfortunately, they were right.
At the end of a calendar round in 1554, Mayan leaders decided that the end to ≥the world as they knew it≤ had come. Exactly 5 calendar rounds later in 1820, many Latin American countries declared their independence from Spain.
What happened on 12/21 /2012?:
The great 25,770 year cycle comes to a completion and returns to where it started. It is believed by the Maya that:
≥This present linear fashion of time will transform into multidimensionality, and will not be limited to linear time on earth much longer.≤
Beyond the limited perceptions of and on this planet and solar system lies a cosmic scheme of underlying order in which the earth’s spiralaic flow of history unfolds in patterns of time. The cycle of light will come in full force on 12/21/2012.
We are now living in the last Bπaktun cycle of the last 5,125.36 year cycle of the 25,770 year ≥great cycle≤. 0.0.0.0.0 is actually the same date as 13.0.0.0.0 since the cycle repeats itself until the last cycle ( thatπs the one weπre in). On 12.21.2012, the winter soltice sun will cross a point in the galaxy that it only does every 25,770 years. Functioning accurately though the ages, the Maya Calendar curiously stops on 2012.
On the more mystical side, the 2012 end date coincides with the end of the ≥Age of Aquarius≤ that we are now in. It is important to note however that traditional astrology is based on 2000 year old constellation positions that are no longer true. Maya astrology is concerned with the ≥big picture≤ and correctly compensates for the movement of constellations relative to the ecliptic over time.
Astro-Specifics
Astronomically, the winter solstice is a one of two days a year where the sun is farthest away from the celestial equator. For an in depth explaination of solstice and equinox go here: http://skyandtelescope.com/aboutsky/pressreleases/article_889_1.asp
The ecliptic is the path of the sun in the sky which is marked by the constellations of fixed stars. Here the moon and the planets can be found because they are bound, like the Earth, to the sun. The winter and summer solstice occur on the ecliptic. The constellations on the ecliptic are also called the zodiac.
Precession
Every year the solstice occurs at a different point on the ecliptic as the earth slowly precesses. In other words, the earth wabbles or gyrates as it spins due to torque created by other heavenly bodies (primarily the sun and moon) and therefore has cycles of non-perfect elliptical orbits of the sun. The north pole sweeps out a cone shape in the celestial sphere. The circle this cone scribes has a diameter of 46.878 degrees.
Although the Babylonians were aware of the changing of the constellations, the Greek astronomer Hipparchus of Nicea discovered this phenomenon around the year 130 BC. Comparing other ancient observations and by evaluating the shadow cast by the Earth on the Moon during a Lunar eclipse, he determined that the celestial intersections had moved about two degrees in 169 years. Note that Maya knowledge of this cycle greatly predates the Greeks and dates back as far as 3114 BC.
The complete cycle takes 25,770 years and yet the solstice points are never exactly repeated. The precession cone itself wobbles due to the gravitational effects of other celestial bodies. Because of this the path of the ecliptic varies with respect to the Galactic Center.
At sunrise on December 21, 2012 the winter solstice Sun rises to conjunct with the plane of the Galaxy or otherwise known as the Galactic equator at point C on chart. This plane travels down the middle of the cloudy Milky Way and includes the point: the Galactic center.
The Galactic center is in Sagittarius at R.A. 17 h 39.3 m and Dec. -28∞55¥.This exact point can only be known by measuring radiometric data in the K band. The center is impossible to determine directly at visible wavelengths because of the great amount of extinction caused by the interstellar dust. However, longer wavelength radiation can penetrate the dust and some fine images of the galactic center region have been obtained at infrared and radio wavelengths. This center is now believed to be comprised of black holes ≠ which would account for the bizarre properties observed.
This crossing of the path of the ecliptic and the Galactic equator creates a cosmic cross – what Maya called the Sacred Tree, the Tree of Life.
The Galactic dirt on 2012
The accuracy of the cycle time for a complete precession circle is quite astounding, beyond anything deemed calculable by the ancient Maya. Yet any solstice date from 1980 to 2011 has a closer conjunction. Actually, the closest conjunction within this 26,000 year cycle already took place on December 21, 1998 [proximity to Galactic plane: 33 seconds].
It seems by using just this proximity of conjunction with todayπs Galactic plane, there is nothing special about the date 2012 [proximity to Galactic plane: 12 minutes 19 seconds]. However, it may well be that the position of other planets and/or stars in addition to the Galactic conjunction play a part in the importance the Maya gave to this date. Also, other than the 31 or so years that the solstice conjunction is similar, the last time it got this close was a similar group of years around 49670 BC and the next time it will get this close will be in a group around the year 27549 AD
A few researchers believe the calendar end date is not even in December but maybe October 28, 2011. This is based on the idea that the long count is not precession based (man, materialistic) but connected to divine light. Others say a ≥temporal hierarchy of creation cycles≤ that cause time distortions and ambiguity of the Dresden correlations prevent determination of the actual end date.
Maya architecture
The Maya priesthood relied heavily upon astronomical and derived mathematical data that they compiled in observatories developed as a purposeful part of the architecture of their urban construction. In order to do this the Mayan architectural scheme for the urban areas consisted of a layout plan in which the four regional capitals of the Mayan civilization were purposefully laid out to represent the four corners of the universe; in this plan, then, all gathered astronomical data could be used to mathematically and allegorically represent the universe according to the desire of the Mayan gods.
One example: A mountaintop was artificially leveled (probably by the shear power of Mayans themselves who, purportedly, were unaided by draft animals and wheeled carts) at Monte Alban (a Zapotec ceremonial center) in 250 B.C. in order to construct an astronomical observatory, the main feature of that whole urban layout. This was accomplished at that location so that the Astronomer-Priest (a main scientific-religious figure in the culture) could receive and interpret heavenly data for use in religious and practical interpretation for the Mayan people.
In 843 A.D. the Maya suddenly abandoned their great cities. Chicen Itza, Tulum and other archeological sites represent their most dramatic and lasting achievement, their actual calling card -monuments which recorded in a very precise manner the correlations between the galactic harmonic pattern and the terrestrial solar calendar.
This picture of the Pyramid of the great city of Chichen-itza demonstrates the Phenomenon of the Equinox of Light and Dark that reveal the serpents body. This phenomenon occurs only at sunset on March 21 and September 21. It shows us the cosmic serpent of Kukulcan on the slope of the pyramid and represents the creation clearly with the seven triangles of light (that represents the 7 days) and six triangles of darkness (that represents the 6 nights) The 13 Uinals. 13 Cycles of the Divine Creation, observe the rhythm process of creation, waves of light and dark that formed this dimension. Interesting, the Biblical account of creation also accounts for 7 days and 6 nights.
A few more interesting facts:
There are 13 dimensions above us. Current theoretical physicist are able to resolve all competing string theories with a new theory that incorporates 13 dimensions.
Mayan prophets new of their impending European destruction and ≥Elders≤ in existence today supposedly still have all the lost knowledge.
There is only a 648 year difference between the creation of Adam according to the Jewish calendar** and the advent of manπs creation in the Mayan calendar.

Mayan Culture: The Desires of the Gods
In the culture of the Maya, especially during the height of their Classic Period (300 A.D. – 900 A.D.), what we now know as their disciplines of religion, philosophy, prophecy, astronomy and science seemed to be viewed and practiced by them in an holistic manner. Each discipline supported the other and no one discipline was asserted without the help and approval of the others. Their astronomical observances, being sensitive to the cyclical nature of the sun, moon and planets (i.e., the universe as they knew it), provided the information to develop explanations for creation, religious ritual, philosophy of life and living, and everyday practice in real life. All seemed to blend together into a rather holistic world view and societal reality.
Important to the Quiche language Mayan creation story is the point that death must be overcome first before humanity could be created. In the Popol Vuh (“The Council Book”) sacred text that survived the Spanish conquest and destruction of the 16th century, the gods attempt to create human beings before the rest of the universe is brought about, and they are not successful; they have to destroy their human experiments and start all over. Eventually the gods discover that two undergods, One Hunahpu and Seven Hunahpu, must defeat the Lords of Xibalba (the gods of death and the underworld) before these two can become the sun and the moon; only after the creation of the heavenly bodies, then, can humans be created in a way acceptable to the gods.
The Maya priesthood relied heavily upon astronomical and derived mathematical data that they compiled in observatories developed as a purposeful part of the architecture of their urban construction. In order to do this the Mayan architectural scheme for the urban areas consisted of a layout plan in which the four regional capitals of the Mayan civilization were purposefully laid out to represent the four corners of the universe; in this plan, then, all gathered astronomical data could be used to mathematically and allegorically represent the universe according to the desire of the Mayan gods.

This was accomplished at that location so that the Astronomer-Priest (a main scientific-religious figure in the culture) could receive and interpret heavenly data for use in religious and practical interpretation for the Mayan people.
Mayan Mathematics: “Their (Mayan) system of mathematics was an achievement not equaled for centuries in Europe.”
Conclusion:
The Maya prove that ancient man was not intellectually inferior to modern man. How they were able to measure and predict an astronomical period that outlasted their civilization by a factor of 5 we will never know. Unlike our contemporary science, for the Maya, Science and religion were one. There was no contradiction. The search for truth was the search for the truth of God.
They believed deep truths were given as signs in the heavens by the divine and they discovered these intricate and real relationships between the planets, sun, moon and our place in the galaxy. This is proof of design and not random evolution.
Our so-called ≥advanced≤ science has just recently provided empirical evidence of the calendarπs importance and it shines new light on the age old questions of mankind. Things do exist for a reason. The reason is a divine cosmic one. For those that seriously engage in a study of the Mayan Calendar this soon becomes evident and the former materialistic worldview loses all relevance.
Without special divine revelation, they affirmed a cosmos that testified to divine intelligence and to a creation that contained its own testimony of higher states of truth and existence. An ancient Mayan prayer asks for the gift of understanding. Instead of intellectual pride being used to replace the need for God, they used this gift to worship, honor and exult their concept of the divine.
The Bible records the coming of the Jewish Messiah, Yeshua HaMasiach (Jesus Christ) was divined by interpreting the stars. Wise men or Magi astrologers from the east correctly discerned the Son of Godπs birth. Yes, there exist dramatic celestial evidence which support an important astrological/astronomical event dated within scholarly approximations of Christπs birth date.
The Mayan Calendar stands as an accurate schedule of the Cosmic Plan, of the unfolding of all things that come into existence, and the cycles or waves and harmonic convergence that proclaim human events or possibly even govern manπs fate.
Similarly, Solomon, the wisest man that ever lived said;
≥ There is a time for everything, and a season for every activity under heaven:
a time to be born and a time to die,
a time to plant and a time to uproot,
a time to kill and a time to heal,
a time to tear down and a time to build,
a time to scatter stones and a time to gather them,
a time to love and a time to hate,
a time for war and a time for peaceä
Yes, the Mayan calendar is still in operation today. It predicts a rapidly approaching moment where the current creation will end and a new one will begin. The Bible talks about a similar event, the coming of Messiah and his establishing of a new order a millennium or 1000 year era:
“And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain, for the old order of things has passed away.”
Book of Revelation 21:4
Notes:
* the exact correlation of Mayan and Gregorian dates could be off. Possible range for the Mayan Calendar end dates are from : 1950 to 2050. 2012 was defined by the Thompson Project. Jose & Lloydine agreed.
**Pope Gregoryπs calendar, mandated in 1583 is the only calendar in the world that does not intercalate at least two celestial cycles. The Jewish Calendar is a lunisolar calendar in use among Hebraic peoples ,reckoning from the year 3761 b.c., the creation date of the soul of Adam. The Jewish day starts at sundown.
*** Belief in the 584,283 correlation is based on the Calendar Round dates in use both during the conquest and maintained by some of the highland Maya today. The 584,285 correlation is based on the relationship between astronomical events recorded by the classic Maya and the times these events were known to have ocurred. 584,285 assumes that a 2 day “slippage” has taken place over time. 584,283 was the more widely accepted correlation until quite recently, when a shift towards 584,285 began. A supporting factor much in favor of the latter was the discovery that the text on a stela at Quirigua and the Dresden Codex, written centuries apart, both give the same date for an eclipse, one that matches the 584,285 correlation.
