Contemporary esoteric systems almost invariably play on the desire of mankind to seek or acquire knowledge. Almost universally neglected in such systems are the--often-unrecognized--barriers that prevent knowledge and understanding. Before learning can take place, certain conditions and basic factors must be in place, in the individual or the group. Building on the foundations laid in Learning How to Learn and The Commanding Self, Idries Shah illuminates those factors in Knowing How To Know. Like an ultra-violet light shone onto the petals of flowers, it reveals concealed patterns, normally invisible to our customary modes of thought. "This would not be a book by Shah if it were not often very funny. In short, those who know Shah"s work will not need to be told it is a cornucopia of very various delights; those who do not may find it a fascinating introduction to the Sufi view of life." --Doris Lessing, The Sunday Telegraph
