Prabhupāda: Well, why you are making . . .? We are talking of philosophy. That is applicable to the Muslim or to the Hindus or everyone. When there is right cause of fight, one must fight. This is philosophy.
Guest (2): Yes, but what is the basis on which you decide whether a cause is right or wrong? There should be a common basis. You see?
Prabhupāda: Just like aggressor. Aggressor. Just like you are living in this room. If somebody enters your room and attacks your wife, you must fight. You immediately kill him. That is the law. This is fight. You cannot see your wife being insulted before you. You must fight. You must kill him. That is the law. Aggressor.
Guest (2): Does this apply to the brāhmins?
Prabhupāda: You should fight to the . . . no, brāhmins will not fight; the kṣatriyas will fight. The brāhmins, kṣatriyas, they are part and parcel of the same unit. Just like hand. Hand is the part of your body. When there is attack, you first of all spread your hand. So this is kṣatriya's business. When somebody is coming to attack you, you don't put your legs, you put your hands.
And the hand is raised by the order of the brain. And the hand and the brain is maintained by the belly. Why don't you study your own body? As in your own body there is brahminical department, there is kṣatriya department, vaiśya department and śūdra department. (laughter) But nobody is less important.
