Grant described Eastern Mysticism as his first love, and he immersed himself in Advaita in the early 1950s, devoted to such sages as Ramana Maharshi, Thakur Haranath and Anandamayi Ma amongst others, writing articles for Asian journals throughout the 1950s and 1960s, many of which were subsequently published in At the Feet of the Guru. Discuss here any aspects and developments of eastern mysticism, advaita and related subjects.
