I just want to quickly say that you cannot declare what someone’s “varna” is by looking at their horoscope! Especially not by simply looking at the Nakshatra of their moon. If you want to get some idea of where they most likely are on the spectrum of various varnas, for the purpose of selecting an ideal career – you can do that, if you blend the nakshatra in with the varnas of the rashi, navamsha, and planets. Here is an old example I once gave in this regard: Career Assessment in Vedic Astrology.
You cannot look at a horoscope and say – “you are a shudra” or “you are a vaishya” etc. etc. It is absolutely preposterous to anyone who understands the difference between the pre-modern, corrupt caste system and the beautiful, ancient varna system. The horoscope is an artifact of an individual’s birth. Social status based on a factor of birth is caste. It is bogus. The varna system is based on actual behavior and character (“guna and karma“). That is why Krishna declares in Bhagavad Gita catur-varnyam maya srishtham, guna-karma-vibhagasa – “I created the four social classes, differentiated by character and behavior.”
