The Power of Now - excerpt - chapter 7

Now let your spiritual practice be this: As you go about your life, don't give 100 percent of your attention to the external world and to your mind. Keep some within. I have spoken about this already.

Feel the inner body even when engaged in everyday activities, especially when engaged in relationships or when you are relating with nature. 

Feel the stillness deep inside it. Keep the portal open. It is quite possible to be conscious of the Unmanifested throughout your life. You feel it as a deep sense of peace somewhere in the background, a stillness that never leaves you, no matter what happens out here. You become a bridge between the Unmanifested and the manifested, between God and the world. This is the state of connectedness with the Source that we call enlightment.
