Our only request is that you are all students—you do not neglect this subject matter, this science to understand what is the soul. It is a fact. No scientific professor at the present moment can explain what is that thing missing, when this thing is missing, this body is called dead. What is the distinction of this dead body and the living body? So according to Vedic instruction, according to Kṛṣṇa's instruction, the body is always dead. But so long the soul is there, it appears to be living. Just like within your coat and shirt, so long you are there, the hand of your coat appears to be moving. Actually, the shirt or coat has no body, but because the original body is moving we see the shirt and coat is also moving. Similarly, this body is moving because the soul within, it is moving. As soon as the soul is out of this body, this body will not move.
So this science is very important science. That is the basic principle of understanding. It is not the question of thinking that one may believe in the existence of soul or one may not believe. But fact is fact. "Two plus two equal to four"—that is science. If somebody does not believe, if somebody says, "Two plus two equal to five" or "three," that is not scientist. Similarly, we may not believe in the existence of soul, but that is a fact. But if we want to study the subject matter very seriously and scientifically, then it will be possible to understand.
