Bhagavad Gita 16.10
Giving themselves up to insatiable passions, hypocritically, self-sufficiently, and arrogantly, cherishing false conceptions founded on delusion, they work only to carry out their own unholy purposes.
काममाश्रित्य दुष्पूरं दम्भमानमदान्विताः।मोहाद्गृहीत्वासद्ग्राहान्प्रवर्तन्तेऽशुचिव्रताः॥kāmamāśritya duṣpūraṃ dambhamānamadānvitāḥ|mohādgṛhītvāsadgrāhānpravartante'śucivratāḥ||
