Astrology is the study of how planetary and astronomical bodies effect life on earth. No doubt humans have been studying the motions of the stars since the development of a curious mind. By the time mankind developed agriculture and civilization, knowledge of the stars and the cycles of nature allowed villages, cities and empires to survive. They had to know when to plant, when to harvest, when the floods or monsoons came and when winter was on it's way.
Astrological systems were created everywhere humanity flourished, on every continent. There is a different method of astrology for every culture that existed in ancient times, and in the age of information, they are being brought together and synthesized in new ways.
Although my interests in Astrology branch into many systems, I have chosen to focus on two for my own spiritual path – Mayan and Western.
Mayan astrology is based off of the Mayan Calendar. Despite what you may have heard around 2012, the Mayan's did not falsely predict the end of the world, it was the end of a large astronomical cycle in their calendar, and the beginning of another.
One of the biggest differences between their Calendar and ours, is it's shape and form. The Calendar we use today is linear. We think of time in a straight line with the earliest moment on one end, and the last moment on the other. We work from point to point, reflecting on the past but moving ever onward to a future that spreads infinitely on the horizon.
The Mayan Calendar is circular. Like cogs in a watch, several circular cycles fit near each other, turning the others in it's time. These included:
Though hundreds of these “cogs” existed, I like to focus on one – the Tzolk'in. This calendar was the most sacred to the daily spiritual life of ancient Mayan's because it reflects the energies of creation. It is a 260 day cycle that consists of the combination of 20 day-signs and 13 numbers. Each 13 day cycle is called a Trecena.
