In English
Animals like cattle and birds cannot change the qualities which they acquire with their birth. The lion, for instance, is born as a cruel animal. It lives and dies as a cruel animal. The cat is born with the quality of trapping the rats and of killing them. It lives with these qualities. Try as they may, these animals cannot change their bad and cruel qualities. You can make a cat sit on the chair and give it sathwik food like milk, curd and so on, and try to convert the cat, but the moment it sees a rat, it jumps to kill the rat. Thus, the animal, which is born with cruel qualities, cannot change in spite of our best efforts. However, man is not like that.
