This unique work of a Sufi Master introduces you to the inner circle of Sufi thought. The book contains amazingly frank material that shockingly breaks all stereotypes about spirituality. It is dedicated to how to be and remain a modern person, and at the same time develop oneself in another dimension, as well as how people sometimes miss this chance, turning into exalted esotericists. The book “Knowing How to Know” was published only after the death of the author.
