Hari-śauri: Nainaṁ chindanti śāstrāṇi nainaṁ dahati pāvakaḥ (BG 2.23).
Prabhupāda: Ah, nainaṁ dahati pāvakaḥ. Pāvakaḥ means fire. It is never burned into the fire. It is never cut into pieces with instrument or any weapon. So if you study these two points, anything you take, it can be cut into pieces, within our physical experience. And anything within our physical experience, it can be burned. Even the iron, so hard, it can be burned and liquidified by proper temperature. Even stone, it can be burned, it can be liquidified. The glass, glass is nothing but liquidified stone, everyone knows it. Purified by chemicals, that's all. Then?
Hari-śauri: Na cainaṁ kledayanty āpo.
Prabhupāda: Anything physical, it can be moistened. You keep in the water, it will be soft.Na kledayanty? Āpo?
Hari-śauri: Na śoṣayati mārutaḥ.
Prabhupāda: Mārutaḥ. And evaporation. Even the ocean can be evaporated by the air. So we have got this experience of the five or eight elements. They are physical because they are subjected to be cut into pieces, to be burned into fire, to be moistened, to be evaporated. But it is . . . soul is not affected. Then we have to think of "What is that?" Therefore these scientists, they are puzzled. When the soul goes out of the body, they cannot imagine what thing is missing that the body is dead. Because they have physical ideas. But it is not physical. So everything is described. We have to study thoroughly and apply our brain. The brain must be sharp and finer tissues. Then spiritual understanding will be there. With dull brain, physical brain, we cannot understand. That is not possible. Therefore to spiritualize the brain, the senses, requires a process. Just like to keep a vegetable in frozen condition, it requires a process. Similarly, we have to undergo a process to come to this spiritual platform, to understand the spirit soul, the supreme being, God, and the relationship and the activities. We must adopt the process. And those who are adopting the process, they are making progress. Practical.
So it is not impractical. Thousands of these Europeans and Americans, they, say a few years ago, four, five years ago—say utmost ten years ago—they did not know what is Kṛṣṇa, what is God. But now you ask them, they will explain. They are not foolish, they are not uneducated. So unless they are situated in the spiritual platform, how they are sticking? So there is process, and the process is practical. Anyone who adopts this process, he'll be able to understand. The process is meant for human being. Any human being who will adopt this process will understand. So ask any one of them, these European, American boys, "Are you sticking to Kṛṣṇa consciousness sentimentally or understanding?" Ask them. They will explain, "Yes, understanding." Not blindly. Blindly one cannot stick—that is not possible. So there is God, there is possibility to come in touch with God, there is possibility to serve Him directly, to see Him face to face, if we adopt the process.
