You have to become tolerant. When Krsna was instructed about the eternity of the soul to Arjuna, Arjuna understood it. He said, "My dear Krsna, I quite understand that soul is eternal. Even my teacher and grandfather is killed, he is bodily killed, but he is eternal. I can understand. But do You think that if my brother or if my grandfather or if my teacher with whom I am so thickly connected, if they die, shall I be happy?" So Krsna answered, "Yes. You'll not be happy. Although you know that your son is eternal, he is not dying, he is changing his body... By theoretical knowledge or by understanding, you know it. But who is there in this world who will not cry when the son is dead? He will cry. But that crying is not crying like a layman. He knows that 'My...,' this is habitual. This is habitual."
