Bhagavad-gītā As It Is · Text 3.12
The cycle of sacrifice and duty
इष्टान्भोगान्हि वो देवा दास्यन्ते यज्ञभाविताः ।
तैर्दत्तानप्रदायैभ्यो यो भुङ्क्ते स्तेन एव सः ॥ १२ ॥
iṣṭān bhogān hi vo devā
dāsyante yajña-bhāvitāḥ
tair dattān apradāyaibhyo
yo bhuṅkte stena eva saḥ
In charge of the various necessities of life, the demigods, being satisfied by the performance of yajña [sacrifice], will supply all necessities to you. But he who enjoys such gifts without offering them to the demigods in return is certainly a thief.
