Śrī Kṛṣṇa says,
tāvaj jitendriyo na syād vijitānyendriyaḥ pumān
na jayed rasanaṁ yāvaj jitaṁ sarvaṁ jite rase
na jayed rasanaṁ yāvaj jitaṁ sarvaṁ jite rase
~ Śrīmad Bhāgavatam 11.8.21
“Someone may be able to control their senses temporarily, but unless one can control one’s tongue one has not truly conquered one’s senses.”
