It all starts with the body. Your body is your greatest asset.
Take a seat somewhere. Go inside your body and take a relaxing breath. Become aware of your body. Start at the feet and then expand from there. Sense your awareness of the body growing - become aware of the feet and legs; then feet, legs and torso; then feet, legs, torso, arms and hands. Have a sense of energy growing through the body.
Finally, as you breathe, hold your entire body in awareness - feet, legs, torso, arms, hands and head. Feel into a sense of openness and clarity. Notice any blockages in the flow of openness. Then enjoy three or more clear breaths. Nothing outside the present moment, you and your body.
During the day: try it standing up, or in everyday situations. Notice what undermines your attempts to do the practice.
Quick fix: attempt one full body breath before you begin your next task. Do it as often as you can.
