I've gone through three editions of this book because I keep sharing it with friends. This book is an excellent introduction to Sufism. The use of the divine names, Mullah Nasruddin stories, and meditations are all done well. The book is deep enough to get me thinking, without being so in depth that I get exhausted just looking at it. I keep a copy with me to just open up at random and see what wisdom there might be for the day. There's something in it for dervishes just starting on the path, and dervishes that have been on the path for awhile.
