Billy Doyle felt a strong spiritual orientation early in life, and when in his twenties he came to explore the non-dualistic teachings of Eastern thought, he immediately resonated with them. The teachings of Ramana Maharshi, Nisargadatta Maharaj, J. Krishnamurti and Atmananda Krishna Menon had a profound effect. On encountering Jean Klein, a master of Advaita and Yoga, in 1982, he immediately knew he had met his teacher and spent many years in contact. He lives in London and teaches yoga in the Kashmir Tradition, an approach brought to the West by Jean Klein.
