I had to read this book for a course on Tantric Buddhism and it was so much fun to read. There is a great introduction which explains a bit about Tantra and some of the terminology in the book. The book is about the mahasiddhas or exemplars of this tradition. The book consists of short stories, about two pages each, of the enlightenment and adventures of these religious people. The best part about it is that they all went through these rigorous mental and physical states to reach Enlightenment and none of them got there in quite the same way. There are thiefs, kings, and young women who have interesting and fun tales to read. I would recommend reading some of these stories for children at bedtime but be careful choosing which one, those Tantrics can get a little crazy!
