Read the book and liked it very much because of the intensity of the Swamijis search for spiritual enlightenment. I wanted to take initiation into kriya yoga but unfortunately could not do so, where as my brother whom I have intruduced to the yagoda satsang society took the kriya yoga diksha and it benefitted him very much, since then, recently I have joined the online course, which I am continuing now. A very useful book for serious seekers!
