For a month now I have been an out-and-out vegetarian. The moral effect of this way of life, with its voluntary castigation of the body, causing one's material needs to dwindle away, is enormous. You can judge for yourself how utterly I [am] convinced of it, when I tell you that I expect of it no less than the regeneration of humanity. All I can tell you is: let yourself be converted to a natural way of living, but one in which you eat suitable food (compost-grown, stone-ground, wholemeal bread) and soon you will see the fruits of your endeavours.
