Bhagavad Gita 3.12 — Enjoying without giving
इष्टान्भोगान्हि वो देवा दास्यन्ते यज्ञभाविताः। तैर्दत्तानप्रदायैभ्यो यो भुङ्क्ते स्तेन एव सः ॥
iṣṭānbhogānhi vo devā dāsyante yajñabhāvitāḥ | tairdattānapradāyaibhyo yo bhuṅkte stena eva saḥ ||
Meaning
Pleased by yajna, the gods will give you the things you need. One who enjoys their gifts without offering anything back is truly a thief.
