Woman (2): How do you regard suicide, and would there be any exceptional circumstances that might justify it?
Prabhupāda: Suicide is not justified. Suicide is not justified. It is violation of nature's law. Nature gives you a certain type of body to live in it for certain days, and suicide means you go against the laws of nature; you untimely stop the duration of life. Therefore he becomes a criminal. Suicide is criminal even in ordinary state laws. One cannot make suicide.
Woman (3): I understand that Hare Kṛṣṇa is a scientific movement. Do you think that there is a scientific explanation for the way in which personal enlightenment by simply chanting Hare Kṛṣṇa?
Devotee: The question is that you have said that the Hare Kṛṣṇa movement is a scientific movement . . .
Prabhupāda: Yes.
Devotee: . . . and she wants to know if you can offer a scientific explanation how the Hare Kṛṣṇa mantra can give a person . . .
Prabhupāda: Yes. That is very easy to understand. Suppose you are sleeping, and if I vibrate some sound, you can hear and can wake up. No other method will act. Suppose you are sleeping. Then I have to call, "Mr. or Mrs. Such-and-such, please get up, get up, get up." You get up. Similarly, at the present moment it is our sleeping stage. Therefore this transcendental vibration will awaken to spiritual consciousness. Just try to understand. When one is asleep, the sound vibration can help him. Similarly, at the present moment, in our material condition of life we are sleeping. This transcendental, spiritual vibration will help you. That is the process.
