Why: with the self unattached to external contacts, one finds happiness in the Self, united with Brahman in meditation, one enjoys imperishable happiness, distinguishing external, contact-dependent pleasure from a steadier, internally sourced kind.
In life: pleasure that depends entirely on external circumstances going your way is inherently unstable, since circumstances change constantly.
Teaching: build at least some of your regular sense of well-being from something that doesn't depend on external events cooperating, a practice, a value, a steady relationship with yourself.
