By practice, one should avoid eating in such a way that other living entities will be disturbed and suffer. Since I suffer when pinched or killed by others, I should not attempt to pinch or kill any other living entity. People do not know that because of killing innocent animals they themselves will have to suffer severe reactions from material nature. Any country where people indulge in unnecessary killing of animals will have to suffer from wars and pestilence imposed by material nature. Comparing ones own suffering to the suffering of others, therefore, one should be kind to all living entities. One cannot avoid the sufferings inflicted by providence, and therefore when suffering comes one should fully absorb oneself in chanting the Hare Krsna mantra. One can avoid sufferings from the body and mind by practicing mystic hatha-yoga.
