These monographs are a selection concerning nondual realization. Some were written as a reply to letters from correspondents; others were written as a response to a specific inquiry, resulting from an in-person or telephone discussion, over the years since 1988. The teachings of nonduality have begun to come of age in the West, recognized (at last) as the central essence of Zen, Dzochen, Tao, Vedanta, Sufism, and of Christians such as Meister Eckhart. In particular, the recorded teachings of sages (such as Ramana Maharshi and Nisargadatta Maharaj) have paved the way for a contemporary generation of illuminating speakers and writers.
