I have seen cases where people seemed to become totally free of ego, and at some point in their lives the ego came back. It has happened, for example, to some spiritual teachers. At some point in their lives, they began to identify again with form.
Eckhart TolleI feel that I need to return to the pure stillness periodically. And then, when the teaching happens, just allow it to arise out of the stillness. So the teaching and stillness are very closely connected. The teaching arises out of the stillness. But when I'm alone, there's only the stillness, and that is my favorite place.
Eckhart TolleWhen you become comfortable with uncertainty, infinite possibilities open up in your life.
