II. Paths to the Spirit in East and West
Pure thinking is related to breathing out, just as perception is related to breathing in. We have to go through the same process as the yogi, but in a more inward form. Yoga depends on the regulation of breathing, both in and out, and in this way comes into contact with the eternal in man. What should Western man do? He can transform into soul-experience both perception on the one hand and thinking on the other. He can unite in his inner experience perception and thinking, which would otherwise only come quietly together in a formal abstract way, so that he has the same experience inwardly in his soul and spirit as he has physically in breathing in and out. Breathing in and out are physical experiences. When they are harmonised, we experience the eternal.
