The most important and uncontrollable sense is the tongue. If one can control the tongue, then there is every possibility of controlling the other senses. The function of the tongue is to taste and to vibrate. Therefore, by systematic regulation, the tongue should always be engaged in tasting the remnants of foodstuffs offered to Kṛṣṇa and chanting Hare Kṛṣṇa. Although one may conquer all of the other senses, as long as the tongue is not conquered it cannot be said that one has controlled his senses. However, if one is able to control the tongue, then one is understood to be in full control of all the senses.
