So this Bhagavad-gītā says that those who are trying to make a show of their knowledge, so let them do that. Viśvato-mukham. The universal form, pantheism, monotheism, monism—we have so many theories. But not atheism. You see? So they will have come to this point. And sa mahātmā sudurlabhaḥ. Why does He say, sa mahātmā sudurlabhaḥ? Because the path is not very easy. Spiritual path and to attain complete perfection is not very easy, especially in this age.
In this age we are not living for long time. We are not very intelligent. We may think that we are very intelligent, but we are not intelligent, because we do not know "What I am." Ask anybody, "What you are?" He has the conception of this body. Therefore he's not intelligent. As soon as one will say: "Yes, I am this, such-and-such gentleman, a son of such-and-such gentleman. My country is such and such," these are all false. So nobody knows it. Therefore one who does not know it . . .
Sanātana Gosvāmī—we were teaching in the morning—he said that grāmya-vyavahāre kahe paṇḍita: "Even the laymen, the laymen, they call me a very learned man. I accept it. But actually, I am not learned man." Why? "Because I do not know what I am. If I do not know what I am, then what is the use of other knowledge?"
So actually, the intelligent person who knows his real position, his constitutional position, and his relationship with Kṛṣṇa, then he takes directly this Kṛṣṇa consciousness. And that is recommended in the Bhagavad-gītā and all scriptures. All scriptures. But if you want to go roundabout way, you can go, but you have come to this ultimate point. That is the conclusion.
Then there are divisions of Vedic knowledge: fruitive activities, worship and knowledge. So Lord Śrī Kṛṣṇa is describing about the fruitive activities, sacrifice. In sacrifice we require so many things. Dravya-yajña. By material things . . . we require clarified butter, we require grains, we require mantra, chanting and fire. So many things we require. So Lord says:
- ahaṁ kratur ahaṁ yajñaḥ
- svadhāham aham auṣadham
- mantro 'ham aham evājyam
- aham agnir ahaṁ hutam
- (BG 9.16)
"Now, all this paraphernalia for sacrificing a yajña, for performing a sacrifice—the fire, the butter, the clarified, the wood, and the mantra and other paraphernalia—everything is Myself. Everything I am." That's true, because everything is produced by His energy.
Anything, whatever you take, that's a transformation of energy. Parasya brahmaṇaḥ śaktiḥ sarvedam akhilaṁ jagat (Viṣṇu Purāṇa): "Whatever you are seeing in the universal manifestation, they are simply manifestation of the different energy of the Supreme Lord." Just like in this room, this illumination is the energy of this light.
Therefore we are seeing each . . . one another. Similarly, as the fire is placed in one place but it distributes its heat and light, similarly, although the Lord is in His supreme abode, His energy is acting. The same example: just like the sun planet is far, far away, but its energy, sunshine, is all-over distributed, over the manifestation, material manifestation. So He's everything.
