Let your mind be still and pure.
If you seek longevity, don’t exhaust your body or it’s vitality.
Your eyes should cease from grasping at anything.
Your ears should do the same.
Do not allow your mind to wallow or linger in knowledge.
Let your spirit take care of your body. By doing so, your body can achieve longevity.
Concentrate on the inside. Ignore the outside.
Knowledge when used incorrectly will only harm you.

Chuang Tzu

Emptying your mind and keeping yourself innocent of drawing conclusions from circumstances as they arrive in your purview is not a petition to ignorance. Quite the contrary. Wisdom can only spring forth from a calm and tranquil not moving center. To this end, Taoists often use the expression wu wei. A simple definition of how this phrase works is found in the Tao Te Ching #48

“In the pursuit of knowledge, everyday something is added.
In the practice of the Tao, everyday something is dropped.
Less and less do you need to force things, until finally you arrive at non-action.
When nothing is done, nothing is left undone.
True mastery can be gained by letting things go their own way.
It can’t be gained by interfering.”

Translation: Stephen Mitchell

Anxiety and afflictions occur when we erroneously identify a separate self with this non entity process known as the human body. Thoughts and feelings will always arise and disappear. Just don’t identify with them. When this body-mind identity ceases to control our actions, we then come face to face with all of the great ancestral teachers. Prajna wisdom is exactly this.
