The abandonment of actions with desire, the wise know as saṃnyāsa; the abandonment of all fruits of action, the experts call tyāga.

Terminological distinction: saṃnyāsa = renunciation of kāmya-karma — desirous actions, rituals for material results. This is the order of life of the saṃnyāsin.

Tyāga = abandonment of sarva-karma-phala — all fruits of all action. This is the internal attitude that can accompany any mode of life. The vicakṣaṇāḥ (experts, of clear vision) use these terms thus.
