Khandogya-Upanishad: Third Prapathaka, Tenth Khanda
1. On the fifth of these nectars the Sadhyas live, with Brahman at their head. True, the Devas do not eat or drink, but they enjoy by seeing the nectar.
2. They enter into that colour, and they rise from that colour.
3. He who thus knows this nectar, becomes one of the Sadhyas, with Brahman at their head; he sees the nectar and rejoices. And he, having entered that colour, rises again from that colour.
4. So long as the sun rises in the north and sets in the south, twice as long does it rise above, and set below; and so long does he follow the sovereign power of the Sadhyas.
