When you lose touch with your inner stillness, you lose touch with yourself. When you lose touch with yourself, you lose yourself in the world.
Your innermost sense of self, of who you are, is inseparable from stillness. This is the I Am that is deeper than name and form.
Stillness is your essential nature. What is stillness? The inner space or awareness in which the words on this page are being perceived and become thoughts. Without that awareness, there would be no perception, no thoughts, no world.
You are that awareness, disguised as a person.
