Yantrārūḍhāni māyayā (BG 18.61). It is a machine given to me. Just like you take a car. That is a machine. Now some way or other, if the car stops, not working, does it mean that you are finished? No. I can take another car. This is knowledge. But this knowledge is lacking. People are being educated, but they are all rascals because they have not this simple knowledge that ajaḥ śāśvato 'yam, "I am aja." How it is aja, proof? Yes, there is proof. "How I am eternal?" If somebody asks that "How I am . . .?" (aside) Don't move that body, that. "How I am eternal?" There is proof. And who is giving the proof? Kṛṣṇa, bhagavān uvāca. The highest authority, not ordinary person or any living being—Kṛṣṇa. Kṛṣṇas tu bhagavān svayam (SB 1.3.28). Kṛṣṇa means the Supreme Personality of Godhead. He is saying. He is giving the proof. What is that proof?
- dehino 'smin yathā dehe
- kaumāraṁ yauvanaṁ jarā
- tathā dehāntara-prāptir
- dhīras tatra na muhyati
- (BG 2.13)
Dehinaḥ. I am dehī. Dehī. This is, body is deha, body. But I am not this body. You think over. If you take this finger, you study, am I this finger? No, the conclusion will come: "It is 'my finger', not 'I finger.'" Simply little knowledge required. How? Now, Kṛṣṇa gives this example, that dehinaḥ, asmin dehe yathā dehinaḥ kaumāraṁ yauvanaṁ jarā. He has explained in different ways, but the beginning is this, that this body is changing. You had a small body, baby's body. Where is that body?
