…keeping my heart light by letting go.
If there is even the slightest delicacy in your nature then it is difficult to tolerate. The heart becomes weak and then you cannot tolerate any more. You keep on seeing and listening but rather than truly tolerating whereby you let everything go, you keep it all in your heart until you cannot tolerate any more. Imagine the state of the heart then. Think of the state of your poor mind at that time.
