If we use the word true to mean free of tension then true mind is simply an awareness of connexion, so soft and subtle that there is barely a distinction between awareness and energy. Mind becomes untrue when, out of fear, it tightens and disconnects. Such a mind then has a choice: to conquer fear, relax and reconnect, or to indulge the fear and remain tense and disconnected. This latter course, once established as a habit, leads to the creation of self or ego, which, simply put, is the consolidation of fear and tension. Thinking is the minds attempt to make something meaningful of disconnexion.
