Feel free to leave a review at Amazon.

This hardcover book is the result of the combined efforts of my teacher, Swāmi Shankarananda Giri and myself.

The book defines and explains spirituality in terms that are common to all using language that goes beyond religious and atheistic thought forms. Clarity and distinction is made between true spiritual practices and those that are based on emotion or imagination. The mathematical relationship between spirituality, humanity and the cosmos is explained.

Regrettably the shipping costs outside Switzerland are quite high.  I apologize for this, but there is little I can do in this regard.
