#Punarvasu is a #Nakshatra in Hindu #astrology, which refers to the two brightest stars in the #constellation of #Gemini: #Castor and #Pollux. The stars Castor and Pollux (or in Greek, Polydeukes) were twin half-brothers in Greek and Roman mythology, known together as the Dioscuri. In Latin the twins are also known as the Gemini (literally “twins”)

The word Punarvasu is derived from Puna+ Vasu, which means return, renewal, restoration or repetition. The goddess of Punarvasu is #Aditi (Mother of all Sun Gods)

As per Mahabharata (Śānti.34.96–98), Budha ( #Mercury God) came to Aditi’s home for food and not getting served when he was hungry, he curses her to take re-birth again and again. She was mother for Vivasvān second time. Yima was son of Vivasvan.

If you observe correctly, Sanskrit #Yama is also interpreted as “the twin,” perhaps reflecting an Indo-Iranian belief in a primordial Yama and Yami pair. We can locate parallels between Avestan Yima and Sanskrit Yama, for instance, Yima was the son of Vivaŋhat, who in turn corresponds to the Vedic Vivasvat, “he who shines out”, a divinity of the Sun.

The Gods, the children of Aditi, are basically and essentially are different from children of Diti, who are demons. This nakshatra is all about getting things back to it.

This is the #birth nakshatra of Lord #Rama as captured in Valmiki Ramayana.

“On completion of the ritual six seasons have passed by and then in the twelfth month, on the ninth day of Chaitra month [April–May,] when the presiding deity of ruling star of the day is Aditi, where the ruling star of day is Punarvasu (Nakshatra), the asterism is in the ascendant, and when five of the nine planets viz., Sun, Mars, Jupiter, Saturn, and Venus are at their highest position, when Jupiter with Moon is ascendant in Cancer, and when day is advancing, then Queen Kausalya gave birth to a son with all the divine attributes like lotus-red eyes, lengthy arms, roseate lips, voice like drumbeat, and who took birth to delight the Ikshwaku dynasty, who is adored by all the worlds, and who is the greatly blessed epitome of Vishnu, namely Rama.”
— Book I: Bala Kanda, Ramayana by Valmiki, Chapter (Sarga) 18, Verse 8, 9, 10 and 11
