Life is so much wiser and kinder than your mind imagines. Trust & Be Still.
No thought has any power. You have power. And when you identify and believe in the thought you give power to the thought.
You are the unchanging manifesting as the changefulness
Your heart is the light of this world. Don't cover it with your mind.
Forget about trying to stabilize the personal sense of Self. It is inherently unstable. See that the Self watches this.
The way of the mind is to study many things; the way of the Beingness is to focus on one thing.
