Wisdom means "to see" or "to know". It does not mean knowing facts or having an opinion. Wisdom is uncovered by being present enough to perceive the essence of your whole experience. This wisdom will help you attend to what matters in your life and understand the meaning of your life's changes. The practice of moment-to-moment PRESENCE is key. Seeing essence; knowing wholeness.
Nothing is more difficult than prayer. In all other tasks of spiritual life, however exacting, one can sometimes rest, but there is no rest in prayer, up to the end of one's life.
