On the fifth of these nectars the Sâdhyas live, with Brahman at their head. True, the Devas do not eat or drink, but they enjoy by seeing the nectar.

In plain words: The fifth nectar of the sun belongs to the Sadhyas, a group of heavenly beings led by Brahman, here meaning the creator. The gods do not eat or drink it; they are filled with joy just by seeing it.
