This Kṛṣṇa consciousness practice is turning this material body into spiritual body. How it is done? The example I have several times given, that you put the iron in the fire. The more it is warm, it becomes fire. When the iron is red hot—that when the iron has acquired the qualities of fire—you touch the iron anywhere, it will act as fire. Similarly, this body, although it is material—there are so many examples. A metal, electrified, the metal is not electricity. But when it is electrified, you touch the metal, you get electric shock immediately. Just like the electric wire. Copper, it is copper. But as soon as it is electrified, you touch it, you get electric shock. There are so many examples. Similarly, if your body is spiritualized, then the material action is no more. Material action means sense gratification. So the more one becomes spiritualized, the material demands become nil. No more material activities.
So how you can do that? The same example: You have to keep the iron constantly with the fire. You have to keep yourself constantly in Kṛṣṇa consciousness. Then even your this body, material body, is spiritualized. There is a Sanskrit grammatical law which is called māyātpoktaya (?). Marat(?) means, there is a word, just like svarṇamaya. Svarṇamaya means golden. Golden can be called, when it is made of pure gold, that is also golden. And if it is made of something else but the coating is gold, large quantity of gold, it is also golden. Similarly, when this material body is full with spiritual activities only, this is also spiritual. Therefore saintly persons, of course in your country everyone is put into the grave after passing away, but in India according to Vedic system, only very high personality, devotees, their body is not burned. It is considered spiritual. A sannyāsī's body is not burned because it is considered spiritual. So how it becomes spiritual? The same example: When the body has no more any material activities, simply spiritual activity in Kṛṣṇa consciousness, that body is spiritual.
