If you want to understand that transcendental science, then you have to follow this principle. What is that? Tad viddhi praṇipātena. You have to surrender. The same thing: just like namanta eva. Unless you become submissive, I cannot be a surrendered soul. And where? Where? Praṇipāta. Where you will find a person that "He is . . . here is a person where I can surrender"?
Then that means we have to make a little test where to surrender. That much knowledge you must have. Don't surrender to any nonsense. You have to . . . and how that intelligent or nonsense can be found out? That is also mentioned in the śāstra. That is mentioned in the Kaṭha Upaniṣad. Tad viddhi praṇipātena pari . . . (BG 4.34).
Kaṭha Upaniṣad says that tad-vijñānārthaṁ sa gurum evābhigacchet śrotriyaṁ brahma-niṣṭham (Muṇḍaka Upaniṣad 1.2.12). This śrotriyam means that one who is coming in disciplic succession. And what is the proof that he has come under the disciplic succession? Brahma-niṣṭham. Brahma-niṣṭham means he is fully convinced about the Supreme Absolute Truth.
So there you have to surrender. Praṇipāta. Praṇipāta means prakṛṣṭa-rūpeṇa nipātam: no reservation. If you find out such person, then surrender there. Praṇipāta. And try to serve him, try to please him, and question him, the whole thing will reveal. You have to find out such an authoritative person and surrender unto him. Surrendering unto him means surrendering unto God, because he is God's representative. But you are allowed to make questions—not to waste time, but for understanding. That is called paripraśna. These are the process.
So everything is there. We have simply to adopt it. But if we don't adopt the process and simply waste our time by intoxication and speculation and all nonsensical activities, oh, that is not possible ever. You'll never understand what is God. Because God is not understandable even by the demigods and by the great sages. What is our teeny efforts?
So these are the process. And if you follow, asammūḍhaḥ, asammūḍhaḥ, if you follow the principles and slow but sure, asammūḍhaḥ, without any doubt, if you make . . . that is the . . . Pratyakṣāvagamaṁ dharmyam (BG 9.2). If you follow, you'll understand, yourself, "Yes. I am getting something." It is not that you are in blindness, you are blindly following. As you follow the principles, you'll understand.
Just like if you eat proper, nourishing foodstuff, you'll feel yourself strength and your hunger satisfied. You haven't got to ask anybody. You'll feel yourself. Similarly, if you come to the proper path and if you follow the principle, you'll understand, "Yes, I am making progress." So pratyakṣa . . . in the Ninth Chapter He has said, pratyakṣāvagamaṁ dharmyaṁ susukham.
