Bhagavad Gita 3.6

कर्मेन्द्रियाणि संयम्य य आस्ते मनसा स्मरन्।इन्द्रियार्थान्विमूढात्मा मिथ्याचारः स उच्यते ॥३.६॥

karmendriyāṇi saṃyamya ya āste manasā smaranindriyārthānvimūḍhātmā mithyācāraḥ sa ucyate

He who, restraining the organs of action, sits thinking of the sense-objects in his mind, he of deluded understanding is called a hypocrite.
