Any big man you take, no big man can say that, "I did not commit any mistake in my life." That is not possible. He must commit. He is illusioned; he takes one thing for another. Just like big, big men nowadays at the present civilization, these all of them are accepting this body, "I am this body": "I am Indian," "I am American," "I am Canadian," "I am this, white," "I am black." But no. I am not this body. This is called illusion. So everyone commits mistake, everyone is illusioned, and everyone, because he has got imperfectness and still he wants to teach, therefore he is a cheater. With imperfectness you cannot teach. You cannot teach when so long you say "perhaps," "it may be." So what is this knowledge? That means you do not know. "Perhaps," that means you do not know. "Maybe"– suggestion. All these theories, big, big theories—politician, scientist, philosopher—they simply say "perhaps," "maybe," "missing link." (laughter) This is not knowledge. Therefore we are reading Bhagavad-gītā: śrī-bhagavān uvāca. There is no imperfectness.
Complete knowledge. So if you read Bhagavad-gītā, you get complete knowledge. So what Bhagavān says?
- idaṁ tu te guhyatamaṁ
- pravakṣyāmy anasūyave
- (BG 9.1)
Bhagavān, Kṛṣṇa, is teaching Arjuna. So in the ninth chapter He says, "My dear Arjuna, I am now speaking to you the most confidential knowledge,"guhyatamaṁ. Tamaṁ means superlative. Positive, comparative and superlative. In Sanskrit, tara-tama. Tara is comparative, and tama means superlative. So here Bhagavān says, the perfect Personality of Godhead says, idaṁ tu te guhyatamaṁ pravakṣyāmy: "Now I am speaking to you the most confidential knowledge."Jñānaṁ vijñāna-sahitaṁ. The knowledge is with full knowledge, not that imagination. Jñānaṁ vijñāna-sahitaṁ. Vijñāna means "science," "practical demonstration." So jñānaṁ vijñāna-sahitaṁ yaj jñātvā. If you learn this knowledge, yaj jñātvā mokṣyase 'śubhāt. Aśubhāt. Mokṣyase means you get liberation, and aśubhāt means "inauspicity." Inauspicity.
