Predicated on the immemorial core or "first" principles of the universal perennial philosophy, which finds expression from Lao Tzu to Ramana Maharshi in the East and from Pythagoras to René Guénon and Ananda K. Coomaraswamy in the West, The Higher Spiritual Path details how those on the higher spiritual path must address and master its requirements. This book is as practical as it is philosophical -- or theosophical -- since it is based on the specifics of "sacred science," or spiritual science, an inextricable component of the perennial philosophy. Many of the requirements of the higher spiritual path are based on the truths of this ancient spiritual science, formulated over millennia by jivanmukti, or liberated beings, who serve as the teachers of those currently engaged in treading this hieratic path. The goals of ascending this path are the loftiest; the hierarchical order of its spiritual teachers is the holiest; and the totality of its evolutionary and compassionate purpose is the most sacred.
