Bhagavad Gita, Chapter 3, Verse 12

इष्टान्भोगान्हि वो देवा दास्यन्ते यज्ञभाविताः । तैर्दत्तानप्रदायैभ्यो यो भुङ्क्ते स्तेन एव सः

iṣṭānbhogānhi vo devā dāsyante yajñabhāvitāḥ | tairdattānapradāyaibhyo yo bhuṅkte stena eva saḥ

Translation

"Nourished by the sacrifice, the Gods shall indeed bestow on you the enjoyments ye desire." Whoso enjoys — without offering to Them — Their gifts, he is verily a thief.

— Alladi Mahadeva Sastri

Śaṅkarācārya's commentary

Pleased with your sacrifices, the Gods shall bestow on you all enjoyments. He who enjoys what is given by Gods — i.e., he who gratifies the cravings of his own body and senses without discharging the debt due to the Gods — is a thief indeed, a robber of the property of the Gods.
