So in order to understand... Just like Kṛṣṇa is teaching Arjuna. Before this, Kṛṣṇa surrendered himself. Śiṣyas te 'haṁ śādhi māṁ prapannam (BG 2.7). Although they were friends, Kṛṣṇa and Arjuna were friends... First of all, they were talking like friends, and Arjuna was arguing with Kṛṣṇa. This argument has no value because if I am imperfect, what is the meaning of my argument? Whatever I shall argue, that is also imperfect. So what is the use of wasting time by imperfect argument? This is not process. The process is that we must approach to a perfect person and take his instruction as it is. Then our knowledge is perfect. Without any argument. We accept Vedic knowledge like that. For example, just like stool of an animal. It is stated in the Vedic literature that it is impure. If you touch stool... According to Vedic system, even after passing my own stool, evacuating, I have to take bath. And what to speak of others' stool. That is the system. So stool is impure. One, after touching stool, he must take bath. This is Vedic injunction. But in another place it is said that the stool of the cow is pure, and if cow dung is applied in some impure place, it will be pure. Now, by your argument, you can say that "The stool of an animal is impure. Why it is said in one place pure and in another place impure? This is contradiction." But this is not contradiction. You practically make experiment. You take cow dung and apply anywhere, you'll find it is pure. Immediately purified. So this is Vedic injunction. They are perfect knowledge. We... Instead of wasting time arguing and putting forward false prestige, if you simply accept the perfect knowledge, as they are stated in the Vedic literature, then we get perfect knowledge and our life is success. Instead of making experiment on the body to find out where is the soul... The soul is there, but it is so small that it is not possible to see by your these blunt eyes. Any microscope or any machine, because it is stated it is one ten-thousandth part of the top of the tip of the hair. So there is no machine. You cannot see. But it is there. Otherwise, how we can find distinction between the dead body and the living body?
So here, the perfect knowledge is spoken by Kṛṣṇa:
- dehino 'smin yathā dehe
- kaumāraṁ yauvanaṁ jarā
- tathā dehāntara-prāptir
- dhīras tatra na muhyati
- (BG 2.13)
Dehinaḥ, of the living soul, the body is changing. Similarly, after death, after so-called death... Because there is no death. After stoppage of the function of this gross body, the soul is transferred to another gross body. This statement we get from Bhagavad-gītā. And if we accept this statement, "This is fact," then our spiritual life immediately begins. Without this understanding, there is no question of spiritual understanding. Everything vague, simply mental speculation, "maybe," "perhaps." These theories are being forwarded by so-called scientists and philosophers. But we don't accept such things as "perhaps," "maybe." No. We accept what is fact. It is not a question of belief; it is a question of fact. So this is the fact.
