There are so many causes of agitation, but a person, in spite of being persuaded by the cause of agitation . . . just like a young man and young woman, when they are present, naturally they become agitated. In the śāstras it is said just like fire and butter. If you put butter before the fire, automatically it melts. Similarly, a woman is considered as fire and the man is considered as butter. So this is natural. But a person who is not agitated, he is called dhīra.
So when a man dies, the man's relatives lament, "Oh, my father has gone," "My sister has gone," "My wife . . ." But if you become dhīra, then you are not bewildered. Just like your friend or your father moves from this apartment to another apartment, who is agitated? No, that's all right. He was in this apartment, now he has gone to another apartment, so there is no question of agitation or being perturbed. Similarly, one who knows the causes of transmigration of the soul from one body to another, he is not agitated at the death of his friend or relative. He knows everything, and he knows where his friend has gone with reference to the śāstra.
Just like your friend has gone to India. How do you know? You know that he purchased a ticket for India and he has gone to India, so there is no need of agitation, "Oh, where he has gone? Where he has gone? Where he has gone?" Similarly, when a man dies, one who is dhīra . . . here especially the word is used, dhīras tatra na muhyati. Muhyati means bewildered. Tathā dehāntara-prāptiḥ (BG 2.13). Just like the parents. The child is changing body.
The mother knows, "My child was six inches long within my womb. When he came out, he was twelve inches long, then thirteen inches, fourteen inches, in this way, now three feet, four feet." The mother is not agitated the child is changing body. Similarly, a dhīra, one who knows the laws of transmigration of the soul, he does not lament at the death of his father or friend. He knows that, "My father has now gone to such-and-such place." That also he can know. How? With reference to the śāstra. Therefore Vedānta-sūtra says that you should see everything through the śāstra, śāstra-cakṣuṣā.
Now there is one rascal, he is preaching there is no need of śāstra. Without śāstra, how you can make progress? Just like you are seeing the sun daily just like a disk. But if you, through the śāstra, you see geography, then you will understand the sun is fourteen hundred thousand times bigger than this earth. So how do you know? You have not gone to the sun planet, but how do you know that it is ninety million miles away from your sight and it is fourteen hundred thousand times bigger than this earth? How do you know? Through the śāstra, through the books.
