When they have reached him (the Self), the sages become satisfied through knowledge, they are conscious of their Self, their passions have passed away, and they are tranquil. The wise, having reached Him who is omnipresent everywhere, devoted to the Self, enter into him wholly.

In plain words: When sages reach the Self, they feel fully satisfied by that knowledge. Their strong desires are gone and they are at peace. Devoted to the Self, they become completely one with the One who is everywhere.
