Prabhupāda: Ah. Yes. It is to be learned, just like the electrician learns how to adjust the positive and negative wire, and as soon as it is rightly adjusted there is light. You cannot say: "No, no, why it shall be adjusted like this? It can be done like this." Oh, that will not give you light. You cannot speculate on the science. One plus . . . two plus two equal to four. You cannot speculate, "Oh, can it not be three? Cannot be five?" No, that is not possible. You have to accept this two plus two equal to four.
The same example: so long it was not being adjusted to the right point, there was no light. So this adjustment . . . suppose there is failure in my home. For this adjustment I have to call an experienced man. You may be a lawyer, you may be very nice thinker, but so far electricity is concerned, you have to call for a mistrī, who may not be learned like you but he knows the art, how to do it, expert. Similarly, such a vast subject, to understand God, you do not require the help of an expert?
Guest (1): I did not take that . . .
Prabhupāda: No, no, I don't mean you. Anyone. Anyone. If for ordinary things we have to call for an expert, to understand God is it not necessary to approach an expert? What do you think, Manuel?
Manuel: Yes, . . . (indistinct)
Prabhupāda: That is . . . therefore the Vedas says, tad-vijñānārthaṁ: "In order to know that transcendental science," sa gurum evābhigacchet, "he must go to a guru. He must approach." A guru means not bogus guru. One who knows, expert. But one has to do that. There is no other alternative. That is the injunction of every Vedic śāstra. And this order is from the Kathopaniṣad. Then, on the Bhagavad-gītā the same thing is said, tad viddhi praṇipātena (BG 4.34).
Praṇipāta means surrender. Surrender where? Where to surrender? To a coolie? No, to a superior person, guru. Similarly, Bhāgavata says, tasmād guruṁ prapadyeta jijñāsur śreya uttamam (SB 11.3.21): "One who is inquisitive to understand the spiritual science," tasmād, "therefore," guruṁ prapadyeta, "must surrender to a guru." Just our this morning prayer is guru, beginning of life, beginning of day's work, first worshiping guru.

So in our this Vedic way of life, to accept guru is essential. Even big, big ācārya . . . even Kṛṣṇa, He accepted guru, Sandipani Muni. Lord Caitanya accepted guru, Īśvara Purī. They are perfect, but still, the ways They are showing because They are ācārya. Kṛṣṇa is teaching, taking the part of the ācārya, so He is also accepting, although the fact is as soon as went to, within a few days He learned everything. That is stated in our Kṛṣṇa book.
