Satsvarūpa: Is it all right to use modern machines on our farms?
Prabhupāda: As far as possible don't use machine. Let people be engaged.
Satsvarūpa: Animals?
Prabhupāda: Animal. Yes.
Satsvarūpa: Not gas-driven engine.
Prabhupāda: Let people be engaged. Machine means one man or two man working... That will mean unemployment. Machine means unemployment. The principle should be that everyone is employed. Either brāhmaṇa, either kṣatriya, either vaiśya or śūdra. Nobody should become idle and gossiping, and sleeping, then utilize... This should be principle. Everyone should be engaged in Kṛṣṇa consciousness, then life is successful. And self-sufficient. If we have got spoiling living program, these are necessities. Growing, cultivating, producing, there will be not possibility of, and we don't want more than the necessity. If by God's grace we get more then you can make sale, we are not going to work for selling purpose. Then money will be there. How to get money, how to get money? And as soon as you get money, more than necessity, then sense gratification, then this, that, this, that, then you become implicated. Ato gṛha kṣetra sutāpta... ahaṁ mameti (SB 5.5.8). As soon as you become implicated with material want, gṛha, kṣetra, vittair, ato gṛha kṣetra sutāpta, children, wife, friendship, then the false ego, "I am this body and this is my property," will increase. For that is material world. People do not know the end of life, or the aim of life. They are misguided, hence the Kṛṣṇa consciousness movement to give them an ideal way of life.
