I expected a guide for expanding my spiritual awareness into traditions different than my own. That's not what this book is. It's an autobiography, and the stories about meditation, yoga and art, while deeply personal are not easily applicable, due to their subjective nature and lack of accompanying research from a broader perspective. Even if this book was the guide it pretends to be, it would be insufficient, because spiritual people around and world and across the centuries have used a lot more practices than these 3 he happened to stumble upon.
In the end the book makes me sad, because it is a sad story, even a cry for help, from a confused and insecure spiritual seeker who still hasn't found meaning in his life, is terrified of mortality and insignificance, and doesn't seem to know what kind of God he believes in. Fortunately for him, his social and financial situation afforded him opportunities to explore all kinds of exotic places and training schools while he tried to find himself, but it doesn't look like it helped much. One gets the impression from the stories the 3 spiritual practices he talks about are survival tactics and coping mechanism to him rather than the enriching transcendence tools he wants them to be.
The most tragic part is the event at the Zen Center when he heard the voice of God. It is tragic because the God of his Jewish ancestors talked to him in a way that to me as a Christian observer seems very clear, but looks like he failed to understand to this day what it was all about. First the "Shema" (the most sacred expression of the Jewish faith) identifies the personal God of the Bible, as distinct from the pantheistic God of his Zen masters. Then the irresistible urge to leave that place. Then the precise words he was to speak on his way out: "Thank you for your love" - words that ironically exposed the Zen master for the fraud he was, not just in a complete lack of the love he was thanked for, but unjustified anger and rage to the point he basically cursed Ben by predicting cancer in his future. Jesus says "you will know them by their love" - that's why he was supposed to speak exactly those words, so the true face of the people proclaiming inner peace is revealed, and the deception of meditation while getting God out of your mind is being exposed. But he didn't get it.
I'll say a prayer for you tonight Ben. I hope the time since you wrote this book has brought you closer to the God of your ancestors.
