śhreyān dravya-mayād yajñāj jñāna-yajñaḥ parantapa
sarvaṁ karmākhilaṁ pārtha jñāne parisamāpyate||33||

Meaning : Arjuna, while offering physical things in sacrifice has value, offering with understanding and wisdom is far superior. Everything you do—every action—ultimately finds its highest purpose when it leads you to knowledge of the Self, of Me, and of truth. Knowledge is the goal behind all action.
