Chandogya Upanishad
Prapathaka III, Khanda 9
On the fourth of these nectars the Maruts live, with Soma at their head. True, the Devas do not eat or drink, but they enjoy by seeing the nectar.
He who thus knows this nectar, becomes one of the Maruts, with Soma at their head, he sees the nectar and rejoices. And he, having entered that colour, rises again from that colour.
