For that it must be seen that everything is the self, and it must be known that this is ananta (infinite) and ānanda (bliss). There must be the realization that the 'being' that has no end, is self-sufficient, whatever appears to this being.

Self-sufficiency is the greatest bliss there is. Complete contentment.

Kṛṣṇa states: The one who is liberated in life (jīvan mukta) is both
nityatṛpta and nirāśraya. The latter means 'Detached from, away from (nis)' any basis, refuge, shelter, abode. To stand completely independent as the truth itself, without any dependence on it. By detached from any basis is meant that you are the basis, the truth itself (pure being, pure consciousness). To be independent, because you are the whole. This means the objective fruit of self-knowledge.

Contentment as the subjective fruit and independence as the objective fruit. Brilliant.

tyaktvā karma phalāsaṅgaṃ nityatṛpto nirāśrayaḥ
karmaṇy abhipravṛtto ’pi naiva kiñcit karoti saḥ

He who has given up all attachment to the fruits of his actions, who is always fulfilled within (always satisfied, nityatṛpto), and does not seek his support in anything (independent, nirāśrayaḥ) even though he acts continuously, yet in essence he does nothing.
