Bhagavad Gita 16.17

Self-conceited, stubborn, wealthy, proud, and insolent, they make a show of their patronage, disregarding the norms of propriety.

आत्मसम्भाविताः स्तब्धा धनमानमदान्विताः।यजन्ते नामयज्ञैस्ते दम्भेनाविधिपूर्वकम्॥

ātmasambhāvitāḥ stabdhā dhanamānamadānvitāḥ|yajante nāmayajñaiste dambhenāvidhipūrvakam||
