A new dimenstion to the daily prayers opens up with this modern commentary that has become a classic. Drawing upon a wide range of cources from Miamonides to the Chasidic masters, the author explains the deeper meanings of the morning, afternoon and evening prayers, the Grace After Meals, and the prayer before going to bed. The Siddur, compiled by our Prophets and Sages, is both a tool with which we communicate our thoughts and feelings towards G-d and a text instructing us in the basic tenets of Judaism. When properly understood, it offers a wealth of ethical and moral teachings and sublime concepts.
