I first met Steven in the 1990s when Kyabje Thinley Norbu Rinpoche introduced us and said to me, "Steven is not an ordinary scholar, he is very special" and went on to extoll his genuine connection with the tradition and practice.
Our paths often crossed in subsequent decades, as a lot of my friends studied with him at the California Institute of Integral Studies where he mesmerized a generation of eager Buddhist scholars and practitioners. He was always, warm, joyful, generous, and a delight to be with.
Steven's passing comes on the heels of the publication of his first sole-authored work, The Buddhist Psychology of Awakening: An In-Depth Guide to Abhidharma, which was released two weeks ago. In case you missed it, here is the email announcing the book and talking about Steven and his unique ability to distill a complex topic into a completely accessible presentation.
Steven did see the book, and even signed a few copies for friends.
