My book about breathing techniques “Health & Breath and Life “ is not spiritual, it is a technical book that anybody, who is able to think, can understand and practice. I am not qualified to write about the spiritual aspect of breath.

For anybody who is interested in that aspect, I listed some of the books written by the legendary masters and strong spiritual guides at the end of this book. I recommend looking at those books if you are interested in adding more wealth to your knowledge base.
