Spirituality involves a reconstruction of consciousness and body. It is neither philosophical speculation, nor a symbolic fun from the thinking mind. It is a commitment that requires two conditions: a specific reconstruction procedure worked daily, and a guide because we do not play with the hidden. I am theoretically quite in the spirit of this book. Practically, I ask to see where the work is done in the West, how and with what support. In any case, congratulations to the author for the richness of his work. I hope it lives up to its claims.
