After you wash your hands upon awakening, you should meditate on how you have no existence other than that which comes to you from the Creator, blessed be He. If it would be imagined that, God forbid, the flow of His creative activity stopped, then you would cease to exist. You should think of how the root and source of your life and existence is above, clinging to Him, blessed be He.(Rabi Shlomo of Karlin, Shema Shlomo, I, Hanhagot, p. 1)
