कर्मेन्द्रियाणि संयम्य य आस्ते मनसा स्मरन्। इन्द्रियार्थान्विमूढात्मा मिथ्याचारः स उच्यते॥
karmendriyani samyamya ya aste manasa smaran indriyarthan vimudhatma mithyacharah sa uchyate
Translation
One who restrains the organs of action but sits dwelling on sense objects in the mind is deluding oneself and is called a hypocrite.
Commentary
Krishna exposes false renunciation — sitting still while the mind fantasizes about sense objects is mere pretense. External restraint without internal detachment is hypocrisy. True discipline must come from within.
