Suzanne, I had a used bookstore at one point in my life and was trying to recall what the Zohar was as I know I didn;t carry many mainstream religious books but did carry books on Judaism. I am sure the Zohar presents much of interest. I recall reading James Michener's THE SOURCE and thinking how much suffering the Jewish people have endured over time. It takes courage to embrace a religion outside your usual sphere of experience. I salute your sister for making the effort. She should not fear going to Temple. I went to morning Mass at a small church to get comfortable with the service - could not receive the host but could participate otherwise. Perhaps she can watch something on You Tube that would make her first visit comfortable. When I was in Luther League in Jr. High, our group went to a Temple on a Friday night and a Greek Orthodox church another time. I loved those experiences. She should not fear attending, I am sure she will be welcomed. M.E.
