Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. I believe that this is the first book to be published in the United Kingdom dealing with what may possibly prove to be the most important religious movement in the whole of India. I have been very much impressed by what little I have seen of that movement, and I willingly respond to the request that I should give this book a few words of introduction.
