Bhagavad Gita · Chapter 5: Renunciation in Action

Bhagavad Gita 5.21

bāhyasparśeṣvasaktātmā vindatyātmani yatsukham | sa brahmayogayuktātmā sukhamakṣayamaśnute ||

One whose self is not attached to outer contacts finds the happiness that is in the self. United with Brahman through yoga, that person enjoys a happiness that never ends.

Modern context

There are two sources of happiness. One comes from contact with things outside us: food, comfort, praise, entertainment. The other is found within, in the plain fact of being aware and at rest. The first depends on supply. The second depends on nothing. The verse says that the less a person hangs on the outer kind, the more they find the inner, and that the inner kind does not run out. Outer pleasures are not forbidden here. The point is that the larger store of happiness lies within.
