You'll find those who are animal killers, the so-called Christians and Mohammedans, they cannot understand. They (are) simply fanatics. Cannot understand what is soul, what is God. They have got some theories and they are thinking we are religionists. What is sin, what is pious activities, these things are not understood by them because they are animal killers. It is not possible.
