On the deepest level, what I know for sure is that who I am, essentially, is consciousness and consciousness is timeless and it transcends the body; it transcends the psychological "me," the egoic self. Everybody can know themselves as consciousness.
Eckhart TolleWhen you go deeply into the present, gratitude arises spontaneously, even if it's just gratitude for breathing, gratitude for the aliveness that you feel in your body. Gratitude is there when you acknowledge the aliveness of the present moment.
Eckhart TolleAs you go about your life, don't give 100 percent of your attention to the external world and your mind. Keep some within.
