II. Paths to the Spirit in East and West

In my Philosophy of Spiritual Activity I indicated as a philosophical fact that reality is the product of the interpenetration of perception and thinking. Since this book was designed to deal with man's soul activity, some indication should also be given of the training that Western man needs if he is to penetrate the spiritual world. The Easterner speaks of the systole and diastole, breathing in and out. In place of these terms Western man should put perception and thinking. Where the Oriental speaks of the development of physical breathing, we in the West say: development of soul-spiritual breathing in the course of cognition through perception and thinking.
