We are devotees of Krsna. We are meant for eating the remnants of foodstuff offered to Krsna… If you want to conquer the tongue, then you fix up your mind that you shall not take anything which is not offered to Krsna. Then your tongue will be controlled. Tara madhye jihva ati lobhamaya sudurmati. Tongue is the bitterest enemy of the living being. The tongue is dragging. Jihva. “Kindly give me this immediately. Kindly give me this wine immediately. Kindly give me this tea immediately. Kindly give me this cigarette immediately. Kindly give me this meat.” Why? Control. Krsna says, patram puspam phalam toyam [Bg. 9.26]. So we have to take prasadam, eat Krsna prasadam. Then naturally the other things will be negativated.
