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.

In plain words: A person who understands this fourth nectar joins the Maruts, the storm gods led by Soma, the moon god. Like them, he enjoys the nectar just by looking at it, and he rests in its color and rises from it again.
