This is an in-depth study of the light that is central to enlightenment presented from a mystical Christian perspective. It gives the reader an understanding of light both as metaphor for pure consciousness and the underlying energy of all creation. Though Christian in its language, the unfolding of the narrative incorporates teachings from other spiritual traditions as well; indeed, what will be found here could be called a kind of synthesis of teachings combining the authority of Christ, the compassion of Buddha, and the methodology of enquiry described by such masters as Sri Nisargadatta Maharaj. Subjects like the influence of world thinking, fear and doubt, as well as The Inner Teacher, joy, and awakened awareness are found throughout the chapters, each leading to and complimenting the others. This book will be most helpful to seekers on any spiritual path who are looking for ways to harmonize western and eastern wisdom teachings in a simplistic and practical way. Thus, it is a timely work – as there exist few books in spiritual libraries today that focus on these subjects solely through the lens that we call the spiritual principle of light.
