If you are intelligent enough, you take one ingredient of this body. One after another, one after another, one after another, you analyze. You won't find. Neither with that ingredient you can create life. That is not possible. This is analysis. You are very expert in analyzing things in the laboratory and charge fees, chemical analysis. But this is also composition of these chemical. But they say "chemical evolution." That's right, evolution. It has come, life. Then, when life is lost, why don't you combine these chemicals, bring life? That is not possible. Therefore, by proper analysis one must come to the conclusion that these ingredients are different from the living force. Then . . . That is called self-realization. Ahaṁ brahmāsmi: "I am not this matter." That is the first step of knowledge. Brahma-bhūtaḥ prasannātmā (BG 18.54). "Oh, I was so much busy with this lump of matter. Now I understand that I am spirit soul," ahaṁ brahmāsmi. This is the first realization, self-realization.
Then,
- brahma-bhūtaḥ prasannātmā
- na śocati na kāṅkṣati
- samaḥ sarveṣu bhūteṣu
- mad-bhaktiṁ labhate parām
- (BG 18.54)
Now, after being brahma-bhūtaḥ, realizing oneself that "I am not this body, I am spirit soul," he becomes relieved from all these anxieties. Because here in the material world it is full of anxieties because we are identifying with this body. This is the cause of anxiety. But as soon as I realize myself that "I am not this body; I am spirit soul," then all my anxiety is gone. Na hanyate hanyamāne śarīre (BG 2.20). I am always very much anxious to give protection to my body. But we understand that na hanyate hanyamāne śarīre. Even your body is annihilated, you are not annihilated. That understanding is lacking. One who understands—na śocati na kāṅkṣati, samaḥ sarveṣu bhūteṣu (BG 18.54). Then there is no fight between one nation to one nation, one animal to one animal, one man to one . . . There is no more. Samaḥ sarveṣu. Because that is the realization that "We are not this body." "I am neither dog, I am not man, I am not this, I am not that. This is all superficial. I am spirit soul. A dog is also spirit soul; the snake is also spirit soul; the tree is also spirit soul." Paṇḍitāḥ sama-darśinaḥ (BG 5.18). That is real knowledge, sama-darśinaḥ.
Then next stage is that "I am spirit soul, and I am fallen down in this condition. Now I have realized. But wherefrom I am coming?" That is next research work. And then, when he understands by studying ourself, and when he understands from Kṛṣṇa, Kṛṣṇa said, mamaivāṁśo jīva-bhūtaḥ (BG 15.7), "I am a jīva, living entity. I am part and parcel of Kṛṣṇa," this realization, Brahman realization, Para-brahman realization. Then "I am living force. Then what is my duty?" The duty is the small must render service to the great. This is bhakti. This is bhakti. You analyze simply. It is the most perfect science, bhakti-yoga. That is natural, bhakti-yoga. It is not artificial. Jñāna, karma or yoga, they are all artificial. Simply Caitanya Mahāprabhu begins from this point, jīvera svarūpa haya nitya kṛṣṇa dāsa (CC Madhya 20.108).
