Leigh Brasington studied the jhanas with the late Ven. Ayya Khema, who authorized him to teach retreats on the jhanas. He was also empowered to teach by Jack Kornfield. He teaches numerous jhana retreats throughout the year, at venues that include Cloud Mountain, Barre Center for Buddhist Studies, Gaia House, Vallecitos, and Southern Dharma. This is his first book.
