श्रेयान्द्रव्यमयाद्यज्ञाज् ज्ञानयज्ञः परन्तप ।सर्वं कर्माखिलं पार्थ ज्ञाने परिसमाप्यते ॥

The sacrifice of knowledge, O Parantapa, is greater than any material sacrifice. Knowledge is that in which all this action culminates (not any lower knowledge, but the highest self-knowledge, and God-knowledge), O Partha!
Gītā 4·33…there are gradations in the range of these various forms of sacrifice, the physical offering the lowest, the sacrifice of knowledge the highest. Knowledge is that in which all this action culminates, not any lower knowledge, but the highest, self-knowledge and God-knowledge,…
As the works grow more and more desireless, equal-minded, sacrificial in spirit, the knowledge increases; with the increase of the knowledge the soul becomes firmer in the desireless, sacrificial equality of its works. The sacrifice of knowledge, says the Gita therefore, is greater than any material sacrifice.
