Passion for practice fuels our effort. There are different sources of spiritual passion (four Iddhipadas) that correspond to different temperaments: zeal, effort, love of the Dharma and urgency.
Paying attention...a non-judgemental, non-manipulative, non-grasping, non-rejecting, kind of attention to the body in the body...just the body as such...not one's feeling, ideas, concerns, or interpretations about it. How do we know the body? How are we established in this first domain of mindfulness? Are you looking in the right place and in the right way for the happiness that you are seeking?
