Prabhupāda: Everything. That is proved scientifically. Sir Jagadish Chandra Bose has proved. There is a part(?). What is that? Spi...? Begins the word, the machine, the record?
Devotee (2): Spirograph.
Prabhupāda: Yes, the word begins with s. Spirograph or like that. You do not know? They smear with black, what is called, carbon, and the fine...
Devotee 2: Cardiograph.
Prabhupāda: Cardiograph, like that.
Puṣṭa Kṛṣṇa: Cardiograph.
Prabhupāda: Yes.
Puṣṭa Kṛṣṇa: Sensation.
Prabhupāda: No, no, the machine is called some special name.
Hariśauri: The same idea as cardiograph.
Puṣṭa Kṛṣṇa: Spectograph?
Prabhupāda: Spectograph, yes.
Puṣṭa Kṛṣṇa: Has to do with light?
Prabhupāda: Whatever it may be, it records how it is moving, how it is going up and down. So that has been proved. The machine is hanged in the tree, and the tree is cut, and immediately makes a mark. Sir Jagadish Chandra Bose has discovered the machine.
Puṣṭa Kṛṣṇa: Generally at least, though, we associate the heart with an organ that simply pumps blood and oxygen throughout the body, but the biologists contend that certain bodies and certain species of life have no such circulatory system, pumping blood or even oxygen.
Prabhupāda: Why not?
Puṣṭa Kṛṣṇa: Well, that's the contention at present.
Prabhupāda: Hm. But we can take that...
Guru-kṛpā: Like a worm. If you cut a worm in half, both parts of the worm will go on living.
Prabhupāda: Hm?
Guru-kṛpā: You take one worm, you cut it, and both parts will go on living. You cut it in three places, and it will all live.
Prabhupāda: Yes. So what is the wrong there?
