Rabbi Yehudah Lev Ashlag was a major Kabbalist, opening up the whole field of the Kabbalah by deciphering the code it was written in. He was the author of In the Shadow of the Ladder: Introductions to Kabbalah. Yedidah Cohen, with her husband, translated Rabbi Ashlag's In the Shadow of the Ladder: Introductions to Kabbalah. She teaches at a gifted children's college in Northern Israel and appears frequently on Israel National Radio.

A Tapestry for the Soul takes the Introduction to the Zohar (as translated in In the Shadow of the Ladder) as its main thread, from its beginning to its end. Excerpts from Rabbi Ashlag's other writings are skillfully placed throughout, in order to explain the Introduction to the Zohar in depth. This is a totally innovative way of teaching. The benefits thus obtained include the fact that the reader can follow Rabbi Ashlag's thought directly, without the need for an intermediary to explain his ideas, thus enabling direct contact between the Master Kabbalist and the reader. Now, even the beginner is able to learn from authentic Kabbalah texts.
