Yoga By yoga I understand a system (the realms below) that integrates cognition, emotion, body, and experience—always experimental in means and ends; it is not other than reason and logos. I.e., there is no final expertise in yoga but ongoing experiment and reflection in relation to purpose. Meditation—a part of yoga, is also experimental. It is not only an exercise or a practice (e.g. of quiet, emptiness, or contact with the real) but, in action, brings one back in the moment to the small and large essentials requiring attention—it is a practise in avoiding ruts. Some readings—Pema Chödrön: How to Meditate, Chagdud Tulku: Gates to Buddhist Practice, Bhagavad-Gita, and the traveler Ian Baker: The Heart of the World on nature journey for insight into self (Atman) and world (Brahman).
