By Swami Harshananda
Vaivasvata literally means ‘son of Vivasvān’.
Āditya, the Sun-god, is known as Vivasvān. His wife was Saiṅjñā. Vaivasvata was their son. He is also known as Vaivasvata-manu and Srāddhadeva. He is the seventh in the series of Manus. It is his rule, called Manvantara, that is going on now.
