Indumadhana Mullik. He was engineer, medical practitioner and scientist. Of course he was practicing as a medical man. And a great scholar. Great scholar, he, he used to study; he passed in engineering examination, medical examination and ordinary M.A., Ph.D., like that. Later on he became so mad, and naked he was running on the street, in front of my father-in-law’s house. So what was his value? The same man, being so much educated in so many… But when he became mad, who cares for him? So this… Anyone who is under the influence of this material energy is like that. Although he is part and parcel of God, he is mad.
pisaci paile yena mati-cchanna haya
maya-grasta jivera se dasau
[When a living entity is conditioned by material nature, he is exactly like a person haunted by a ghost.]
As soon as a man becomes mad, then he is finished. And whatever he’ll speak, ah, that is all madness. It is…, there is no importance. This is mad. Basic principle is mad.
