We categorize the Nakshatras into three groups: divine, human, and demonic. Gender and Varna (caste) divide people. They have assigned qualities, such as colour, deity, and rulership. When studying how a planet affects a sign, look at where it is in relation to Nakshatra and Pada. Indians have used Nakshatras for centuries to pick fortunate dates and times for events, such as weddings. The role of Nakshatras and their respective Padas in predictive astrology is unique to Indian Vedic astrology.

These celestial luminaries make all the difference in astrological calculations. Initially, the zodiac was grouped in 12 Rashis for convenience, however the ancient seers have farther subdivided the heavens into 27 Nakshatras or star constellations for the call of precession. These constellations or the Nakshatras emerged as one of the most important components in Astrology.

Vedic astrology identifies each constellation with a star. The 360 degree division of the sky is therefore further divided into 27 subdivision of 13.20 degrees identified with 27 stars. Each of these Nakshatras are farther subdivided into four Padas or quarters of 3 degrees and 20 minutes.
Therefore the first Rashi, Mesha, which has 30 degrees, contains the entire 4 Padas (13:20′) of the 1st star constellation Ashwini, the entire 4 Padas (13:20′) of the 2nd star constellation Bharani and the 1st Pada (3:20′) of the third star constellation Krittika. In this manner, each Rashi comprises of 9 Padas. Some schools of astrology also consider 28 divisions with an additional star called Abhijit. However, for all practical purposes only 27 stars starting from Ashwini are considered. (Ref: the chart).
