Bhagavad Gita, Chapter 2, Verse 55

The Deity said: When a man completely gives up, O Pârtha, all the desires of the mind, content in the Self alone by the Self, then is he said to be one of steady wisdom.

Real contentment starts the moment you're not constantly chasing the next craving.

Most cravings promise satisfaction and never quite deliver it, like chasing something that keeps moving further away. Contentment shows up not by getting more, but by no longer needing to chase in the first place.
