Whatever is available easily we can use. There is no objection to using electricity. But we should not be dependent upon it. Produce oil from castor seeds and stock the oil sufficiently. It can be used in so many ways—for burning, grease, cooking, and as a purgative to cure all diseases. And oxen can be used for driving carts and go preaching village to village. What is the question of killing them? Here in India our Lokanatha Maharaja has successfully organized such a program and it is a great success. He has traveled all over India and everywhere they distribute books, prasadam and perform kirtana. Each night they stop at a different village. We can introduce many millions of such carts all over the world.
As far as possible try to adjust to a natural way of life free from dependence on machines. But our principle should be that we are against nothing and for nothing. Only for Krishna. We want whatever is favorable for Krishna. From the farms we should get sufficient foodstuffs and these can be sent to be used at our restaurants. Along with the restaurants there can be "Bhaktivedanta Reading Room" where all my books can be kept and people can come and sit comfortably and read. The people will like these restaurants and reading rooms. They will take them as non-sectarian.
