" may not, now or hereafter, enter into a detailed account of the experiments in dietetics, for I did so in a series of Gujarati articles which appeared years ago in Indian Opinion, and which were afterwards published in the form of a book popularly known in English as A Guide to Health. Among my little books this has been the most widely read alike in the East and in the West, a thing that I have not yet been able to understand. It was written for the benefit of the readers of Indian Opinion. But I know that the booklet has profoundly influenced the lives of many, both in the East and in the West, who have never seen Indian Opinion. "
