Calling themselves Sai devotees or devotees of Rama and Krishna, they fatten on chickens. But animals are endowed with mind, and nervous systems too while the plants do not possess the same. The animals cry and weep when they are being killed. Hence, meat eating should be discarded. Food conditions the nature of the mind.
Mind guides the thinking.
Thinking results in action. Actions lead to commensurate or matching results and effects. This chain of action between the food we eat and the results of our actions highlights the fact that meat eating leads to beastly actions and the concomitant evil effects. There is nothing wrong in this. It is only God that can take them and bestow His grace on you to foster good qualities.
