One of Paul Brunton’s truly significant contributions, this volume offers a mature spiritual perspective on the importance of character development, personality refinement, and proper use of the thinking faculty. Part 1, Emotions and Ethics explores two fundamental relationships. The first is that between character development and spiritual progress; the second is that between personality refinement and spiritual self-expression. Part 2, The Intellect explains the important role, and the limitations, of the thinking faculty as a transformative potency in spiritual practice.
