This body is kṣetra, field of activity. Just like we are in Bombay, everyone is busy actively. So Bombay is the field of activity; you are not Bombay. If one identifies himself with this Bombay city—"I am Bombay"– this is foolishness. Bombay city is different from me, but I am working in Bombay city in different capacity. This is knowledge. Just try to understand, that people are identifying that "I am body." This is not good.
- kṣetra-jñaṁ cāpi māṁ viddhi
- sarva-kṣetreṣu bhārata
- kṣetra-kṣetrajñayor jñānaṁ
- yat taj jñānaṁ mama
- (BG 13.3)
People are... People are very much proud of their knowledge. But Kṛṣṇa says that knowledge means kṣetra-kṣetrajñayor jñānaṁ. Knowledge means to know the field and the actual proprietor of the field. Kṣetra-kṣetrajñayor jñānaṁ yat taj jñānaṁ. That knowledge is real knowledge. Mataṁ mama: Kṛṣṇa is giving His opinion. Now clearly, if we identify the kṣetra and the kṣetrajñayor are two, mixed up, that is ignorance. That is not knowledge. But just try to understand, people are under the impression that "I am this body." This is not knowledge; this is ignorance.
Then He says, kṣetra-jñaṁ cāpi māṁ viddhi. Yesterday we discussed the first verse, that,
- idaṁśarīraṁ kaunteya
- kṣetram ity abhidhīyate
- (BG 13.2)
Kṣetram ity abhidhīyate. This body is the field of activities, and,
- idaṁśarīraṁ kaunteya
- kṣetram ity abhidhīyate
- etad yo vetti
- (BG 13.2)
And one who knows this,
- etad yo vetti taṁ prāhuḥ
- kṣetra-jña iti tad-vidaḥ
- (BG 13.2)
One who knows perfectly that "I am the proprietor of this body. I am utilizing this body for my purpose. The body is made of matter, and I am the spirit soul, part and parcel of Kṛṣṇa," this is perfect knowledge. This is perfect knowledge. And one who foolishly identifying that "I am this body: I am this hand, I am this leg, I am this blood, I am this stool," he's not in knowledge. He's not in knowledge.
A combination of blood, stool, urine, muscle, bones—does it mean a spirit soul? Can you do it? There are many philosophers, they say that the combination of these bones, muscles, all the material things, produces the living energy. But why don’t you do it? Eh? There are so many opportunities, so much opportunity that you can get blood also, bone also, and flesh also, urine also, stool also—why don’t you manufacture a body?
Manufacture a body. No, it is not possible. These material things grow on the spirit soul. When the spirit soul takes shelter into the womb of a particular mother, then these things grow. Seed. Seed is the spirit soul. Just like a seed of a big banyan tree: you put within the earth and take care, put water, it will grow, a very big tree, with thousands and millions of figs. And in each figs, thousands and millions of seed. And each seed containing another tree. This is creation of God.
So matter does not produce living force. The living entity produces matter. This is the philosophy. Matter is their opinion. The Buddha philosophy, Jain philosophy, they do not believe in the existence of God as the origin. But this matter, when combined together, it produces a living force. But that is not the thing. Living force, or the living entity, produces matter. Try to understand. Matter does not produce living entity. That is not fact. The living entity produces matter. Therefore this gi... Similarly, the supreme living entity, Viṣṇu, He has produced this gigantic material cosmic manifestation. He's the root.
