There are many theories and philosophical speculation all over the world about understanding the soul. Therefore Kṛṣṇa is concluding that "Somebody's explaining wonderfully, somebody is hearing wonderfully, but even after hearing and speaking, it remains a mystery, and less intelligent person cannot understand it." That is the fact. There are so many theories. Therefore we have to accept the reality from the authority. By theorizing, by speculating, we cannot come into any decision. I may be very good logician. You may be greater logician. So you can defeat my logic. I can defeat your logic. So what is the conclusion? This kind of talking, it is called ku-tarka, unnecessarily talking, because you'll not come to my decision, I'll not come to your decision. So everyone is mysterious.
So in this way we cannot understand which is beyond the perception of our knowledge. Acintyāḥ khalu ye bhāvā na tāṁs tarkeṇa yojayet. Things which are beyond our perception, you, we should not simply try to understand by logic and argument. It is useless waste of time, because nobody can decide theory. The modern so-called scientists, they also write like that: "Perhaps," "It may be," like that. "It may be millions of years. It was like this." "It may be." What is the value of saying "It may be." Say definitely. That they cannot do. All the scientists" theory like "Perhaps," "Maybe." "Perchance, if it comes to be true..." So such kind of argument has no value. Therefore our śāstra says: acintyāḥ khalu ye bhāvāḥ. Beyond your perception, beyond your sense perception, don't try to understand it by argument and logic. Then how to know it? Know it from the person who knows it. That is knowledge. Just like we are trying to get knowledge about the soul, not by experiment, but we are trying to understand from the words of Kṛṣṇa. Kṛṣṇa is the authority. So He says, in the beginning: dehino 'smin yathā dehe kaumāraṁ yauvanaṁ jarā (BG 2.13). We can... Kṛṣṇa says, and we can think over it and ponder over it. Then we come to conclusion. And the other process, Vedic process, is:
- yasya deve parā bhaktir
- yathā deve tathā gurau
- tasyaite kathitā hy arthāḥ
- prakāśante mahātmanaḥ
- (ŚU 6.23)
Our process is descending process. We are not trying to understand by the ascending process. Inductive or deductive. We accept the statements of the Vedas. Therefore we haven't got to make much effort to understand a thing.
