The ego doesn’t like to hear this, because if it cannot be reactive and righteous anymore, it will lose strength. (Ch 8) - Eckhart Tolle

Meister Eckhart, the thirteenth-century spiritual teacher, summed it all up beautifully: "Time is what keeps the light from reaching us. There is no greater obstacle to God than time."

What you react to in others, you strengthen in yourself.

Something of its essence then transmits itself to you. You can sense how still it is, and in doing so the same stillness arises within you. You sense how deeply it rests in Being–completely at one with what it is and where it is. In realizing this, you too come to a place of rest deep within yourself. (Ch 7)
