The Jew in the Lotus : Buddhism & Judaism

I recently read a book called “The Jew in the Lotus,” which chronicles the visit of a group of Jews to have a dialogue with the Dalai Lama in India. I was both intrigued and troubled by the continual attempt to show common threads between Judaism and Buddhism. What I’m most troubled by is that I don’t have the knowledge to know if the modes of meditation in Buddhism and Judaism are truly similar, and I was hoping you are familiar with the book and can offer some insight.
