Those who are killing cows, according to the decision of karma kanda, these killers of cows will in the next life be cows, and the cows who are killed will become men and kill the killers. The word flesh is called mansa which means the animal in future will kill me and eat. This is called karma bandhanam, bound up by the laws of karma. If you kill some living being, he will kill you in the next life. According to Manu samhita, the Vedic lawbook, a murderer is hanged and thereby released from sinful activities so that in the next life he may not be killed. Life for life sentence is given to end the result of sinful activities in this life instead of waiting for the next life.
