Bhagavad-gītā As It Is · Text 4.33
Sacrifice, discipline and knowledge
श्रेयान्द्रव्यमयाद्यज्ञाज्ज्ञानयज्ञः परन्तप ।
सर्वं कर्माखिलं पार्थ ज्ञाने परिसमाप्यते ॥ ३३ ॥
śreyān dravya-mayād yajñāj
jñāna-yajñaḥ paran-tapa
sarvaṁ karmākhilaṁ pārtha
jñāne parisamāpyate
O chastiser of the enemy, the sacrifice performed in knowledge is better than the mere sacrifice of material possessions. After all, O son of Pṛthā, all sacrifices of work culminate in transcendental knowledge.
