What's shatbhisha ?
Shatbhisha is the 24th nakshatra that falls in the zodiac Aquarius, the ruling planet is rahu, the deity is varuna. Represented by an empty circle.
Basically if u dunno what nakshatra are they are 27 you can say sections in which the moon travels, after 27 days the moon comes back to the first one, every zodiac has 2-3 nakshatra as nakshatra also have 4 sections (called pad)
The nakshatra in which the moon is on the day & time you were born is called your janm nakshatra and you will have the traits of that nakshatra. Mine is shatbhisha and I have the traits that it represents
