Bhagavad Gita · 3.12

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

iṣhṭān bhogān hi vo devā dāsyante yajña-bhāvitāḥ tair dattān apradāyaibhyo yo bhuṅkte stena eva saḥ

The celestial beings, nourished by sacrifice, will bestow upon you the desired necessities of life. But one who enjoys these gifts without offering anything in return is certainly a thief.
