Letting go of Internal Attachments (Ideas).
The Tao is (like) the emptiness of a vessel; and in our employment of it we must be on our guard against all fullness. How deep and unfathomable it is, as if it were the honored Ancestor of all things! We should blunt our sharp points, and unravel the complications of things; we should attemper our brightness and bring ourselves into agreement with the obscurity of others. How pure and still the Tao is, and if it would ever so continue!
Often we need to attemper our brightness, or make less zealous our messages, temper them with compassionate thought instead of assuming our truth is the only truth for everyone. As we empty our vessels of our attachments, both to the material and immaterial, we then can fill it once more with good deeds, and good Dharmas.
Drop by drop is the water pot filled. Likewise, the wise man, gathering it little by little, fills himself with good. Buddha
