Live life inside out. That is the core principle of the art of mindful, soulful life. Mindfulness is to realize that you are essentially a seeker seeking your own Self! The Self is not a philosophy; it is the reservoir of infinite Wisdom and Bliss. You keep searching for it outside till you learn that not until you retreat back to your inner Source from the peripheral world, that you come face to face with Reality.
Self and the Source are One.
