It is a great pleasure of revise the book and also enlarge it to some extent. In now certainly appears that people have taken a fancy to Gem Therapy as editions are beisg exhausted fast. Western people are taking more interest in this therapy as they realise that there are absolutely no harmful effects from this treatment Another advantage with this therapy is the very low cost, easy preparation and quick administration. I do hope that with so many persons keenly interested in this Therapy it will be regarded as one of the rare inventions of the twentieth century.

My only regret is that Shri Kanailal Mukhopadhyay who always encouraged me with this work is no longer with us. I am-sure he will be blessing from above all those who are engaged in this work.

I am very grateful to Shri Rathin Mukherji, son of Shri Kanailal Mukhopadhyay, who is also giving me all the help which his father used to give me. I wish him a very long and prosperous life to enable him to help authors like me.
