The natural time practice for awakening our natural mind is extraordinarily simple.  The results are Extraordinarily profound.  So before following the instructions below, I invite you to read Jose Arguelles’ article from 2005: Natural Mind, Natural Time. (Note: This article was originally written with the noble yet ambitious goal of Universal Peace by 2012, a whole topic unto itself, but his commentary on natural mind remains more relevant than ever).

Let's begin... It is the most human form and experience you can have, and anyone can do it.
You just have to sit still, with spine erect, seated on a chair with feet firmly on the floor or on a cushion or pillow with legs folded over each other in lotus or half lotus posture. 

Your eyes should be slightly opened looking toward the floor. You may place your hands comfortably on your knees, palms down, or place your right hand on your left hand, palms up, held at the level of your navel. Feel your intrinsic dignity in this posture.

Holding the spine erect is already waking up and staying awake. Now in this position, you have nothing to do but watch your breath. Breathe normally. As you become aware of your thoughts just label them "thinking", and as you exhale, dissolve the thoughts. It matters not the least the nature or content of the thoughts, just dissolve them. At that very moment just as the thought is dissolved lies the "GAP" between the thoughts. It is this GAP you want to become familiar with and cultivate. It is the seed of natural mind and the key to your true, authentic self.

Practice this for at least 15 minutes per day and note the subtle shifts in your perceptions and attitudes. Mind the GAP!
