“The key is to be in a state of permanent connectedness with your inner body, to feel it at all times.
This will rapidly deepen and transform your life.”
(Eckhart Tolle)

Nowadays this meditation is often referred to as the body scan. The goal, however, is not merely relaxation or even falling asleep, though it can also be used for that purpose. It is actually about consciously being present in our bodies at all times. Also after your meditation session or your mindfulness training. The conscious experience of the constantly changing sensations (pleasant – unpleasant) can help us to observe our unconscious reactivity: fight or flight. 
During this meditation you will notice that your thinking activity decreases. The energy needed for this is no longer centered in your head; now this energy flows evenly throughout your body.
Hence the extremely pleasant, spacious feeling.
This alert and allowing state of being is often referred to as “presence” or “the receptive mode”. And of course this can only take place in the timeless NOW.
