Bhagavad Gita 4.33

श्रेयान्द्रव्यमयाद्यज्ञाज्ज्ञानयज्ञ: परन्तप ।
सर्वं कर्माखिलं पार्थ ज्ञाने परिसमाप्यते  ॥

śreyān-dravya-mayād-yajñāj-jñāna-yajña: parantapa
sarvaṃ karmākhilaṃ pārtha jñāne parisamāpyate – 4.33 

Jñāna-yajña, the sacrifice done through wisdom, is superior to the one in which materials are offered. All activities, O Partha, have their culmination in wisdom alone.
