Kāraṇam. We are getting this body according to our association with the different modes of material nature. But Kṛṣṇa has nothing to do with this material nature. Material nature is controlled by Him, and we are controlled by the material nature. That is the difference. He is controller, and you are controlled. They do not understand. They think that if I make null and void these conditions of controlling, then I become uncontrolled.
Just like the philosophy voidism, or suicidism. I am feeling some pain in my body. So if I think that let me commit suicide, then the pain will go away automatically. That is void philosophy. The killing one-self, ātma hā. But because they have no understanding that killing this body does not mean killing yourself. That is their ignorance. In the Bhagavad-gītā it is clearly said, na hanyate hanyamāne śarīre (BG 2.20). So these rascal think if I suicide, if I commit suicide, and just have a knife on my throat, then all my pains and pleasures are finished. No, that is not... He will be put into more pains and pleasure. Sometimes we'll have to accept, why accept, it is certain, the ghostly body. Because Kṛṣṇa has given you, or māyā has given, māyā has given under the direction of Kṛṣṇa, a certain type of body for enjoying for a certain span of life, you cannot finish it. If you disregard it, then, if you commit suicide, the result will be that you will not be allowed to accept another material body. You will have to remain in that subtle body. That is ghost. Ghostly life means one who has misused this life, this body, and by his whims he has killed this body. He becomes ghost. That means he will have to suffer for so many day, then he'll get another material body.
