We have seen practically in India. During the partition days, when the Britishers left India, they gave a parting kick by dividing Pakistan and India. So I have seen in my own eyes there was fighting between the Hindus and Muslims for at least one week in Calcutta, and heaps of dead body there were. So the fighting was between Hindu and Muslim, but when they died, the dead body is piled up and it was taken for burning or to throwing away. So the land remained there, and these people fighting between themselves, that "This is mine, this is mine," they finished their life. The land remained where it was there.
So this is called illusion. Ahaṁ mameti, "It is mine, it is yours." Janasya moho 'yam ahaṁ mameti (SB 5.5.8). Why they should think like that? Bhagavān, in the Bhagavad-gītā He says that sarva-yoniṣu kaunteya mūrtayaḥ sambhavanti yāḥ (BG 14.4): "All the forms of different grades of life," sarva-yoniṣu kaunteya sambhavanti mūrtayaḥ tāsāṁ mahad yonir, "the material world is the mother, and I am the father." Very simply understanding. Everything is grown from the material nature. Our life is also from there. The grass is growing, and the grass is eaten by the animals, and then animals beget another animal. Or vegetables we also eat, and by eating we live. Then by eating we get our semina. Then we beget another children, another child. So actually we are born, every one of us born and nourished by this material nature. This is a fact, one can see. So who is the father? The mother is there, material nature, and we are children there. There must be father.
