Is It Reality Or A Blend Of Reality And Fantasy? . I read this book thirty years ago(do you think I waited long enough to write this review?) and enjoyed it very much, but found it perplexing. I, myself, am a yogi, but this story would strike most people as being a blend of truth and fantasy. But what is wrong with that? It is a beautiful story that teaches us many things about the way yogis look at life--and death. Do not approach this book with a critical eye on truth. Instead, think of it as a type of epic poem. Reflect on the reality of it at your leasure! One thing is true about this book: the author wrote this book with great love of all humanity! If you have developed an interest in some aspect of yoga and want to learn something more of what traditional yoga(as opposed to the "designer" versions touted lately) is about, give this a try
Output:
POS
