These yogas are therefore a type of analytical tool, or a means to inculcate certain analytical habits that can reveal the presence of notable patterns in a chart. Others are a lot more complex, and may involve linking or synthesizing factors in the chart that a superficial analysis would easily overlook. Some are simple, and yet useful, and their purported meaning would be unsurprising and even familiar to a western astrologer, due to all the DNA shared by western and vedic astrology. The Yogas of Jyotish are the fruit of centuries of observation, codified into a rich body of lore regarding the effects of several hundreds of possible permutations of the heavens. The word 'yoga' essentially means to 'join' or 'unite', and here can be translated as an astrological combination or 'union of factors' with specific implications. One of the most intriguing and valuable features of Jyotish is it's vast canon of 'Yogas' and associated aphorisms.
