Bob: Maybe that's just material clinging.
Prabhupāda: So just you follow in their footsteps, my other students, and it will be fulfilled, your desire. We are training to that direction, how to become purified and happy. That is our mission. We want to see everyone happy. Sarve sukhino bhavantu. But people do not know how to become happy. They do not take the standard path to become happy. They manufacture their own way. That is the difficulty. Tapo divyaṁ putrakā yena śuddhyed sattva yasmād brahma-saukhyam anantam (SB 5.5.1). This advice was given by Ṛṣabhadeva to his sons. "My dear boys, just undergo austerity," divyam, "for transcendental realization." Everyone is going austerity. This boy, I know, he had to go foreign countries to learn this commercial management. So many... So now he's good situated. But everyone has to undergo some austerity for future life. So why not take that austerity for permanent happiness? Tapo divyaṁ putrakā yena satt... Permanent happiness, you have to purify your existential body. This body, so long you will accept this material body, you'll have to change it. And as soon as you get a spiritual body there is no question of change. Spiritual body you have already. Simply now, due to our material contamination, we are developing material body. But if we associate with spiritual life, then we shall develop spiritual body. The same example I have several times given, that you put the iron rod with fire, it will develop to be fire. Is it not?
Bob: Put the iron rod into fire...
Prabhupāda: Yes, and it will become fire.
Bob: Yes...
Prabhupāda: Although iron rod.
Bob: Yes.
Prabhupāda: Similarly, this body, if you always keep yourself spiritually engaged, it will act as spiritual, although it is material body. The same example. Iron rod, when it is red hot, it is not longer iron rod, although it is iron rod. You can catch it as iron rod, but touch anywhere it will burn. It has got the quality of fire. Similarly, If you always keep yourself in Kṛṣṇa consciousness then you become spiritualized. You'll act spiritually. No more material demands.
Bob: How do I do this?
Prabhupāda: This process, as they are doing. You have seen. These boys are, our six boys, they are now initiated today. It is very simple. You have to follow the four restrictive regulations and chant this beads. Very easy.
