Why: one who finds happiness within, joy within, and light within alone, that yogi united with Brahman attains liberation in Brahman, again emphasizing an internally located source of contentment as the actual destination.

In life: constantly looking outward for the next source of happiness, a purchase, an event, someone else's approval, keeps you dependent on things outside your control.

Teaching: spend deliberate time each week doing something that generates contentment from within, reflection, a hobby you love regardless of outcome, rather than only from external validation.
