Satsvarupa: But should this be forced on people if they don't want it?
Satsvarupa: If a large section of the people don't want spiritual life, that's their...
Prabhupada: No, you cannot force. That is not possible, because he has got independence. You cannot force. You can simply give him knowledge. Therefore to distribute knowledge is the best welfare activities, not this material so-called happiness, daridra-narayana-seva and this... They have got that. That will not make them happy. If you give them knowledge, then they will be really benefited. Otherwise not.
Brahmananda: How do we give knowledge to the common masses of people?
Prabhupada: Yes, by sankirtana. By hearing, hearing, hearing -- this is a medicinal process -- the heart will be cleansed and they will take up the knowledge. Now the heart is unclean, so he cannot take up. So this is the medicine. Kalau nasty eva nasty eva nasty eva gatir anyatha. Harer nama harer... [Cc. Adi 17.21]. Chant Hare Krsna mantra wherever possible, and whoever will hear, he will gradually become cleansed. Ceto-darpana-marjanam [Cc. Antya 20.12]. And then bhava-maha-davagni... Then his material pangs will be over. This is the only medicine. Therefore chant Hare Krsna. Some way or other, let them have the chance of hearing, and then it will act as medicine. Even he does not will, you chant, you let him hear by force, and he will be cured.
