Classic 4: Song of Thirteen Tactics (Shi San Shi Ge)

The thirteen general tactics should not be underestimated.
Initiate the fulfillment of Yi (intention) at waist level.
During changes and turns from empty to substantial, you must maintain Yi.
Qi flows through the body without the slightest obstacle.
There is immobility even when there is movement;
When there is movement, there is immobility.

In accordance with the opponent, my changes appear mysterious.
Every tactic lies in Xin (thought); the principle is to use Yi (intention).
In the quest for perfection, don't waste Gong Fu (effort).
Sculpt and sculpt Xin (thought) again, at the waist.

Internally, the abdomen is relaxed and still, and Qi rises,
When Wei Lu (coccyx) is Zhong Zheng (adjusted with the center), Shen (mind) connects with the top of the head.
The whole body feels light and agile when the top of the head is suspended.
Be meticulous and keep Xin (thought) when researching art.

Freely contract and lengthen, open and close and listen.
To get through the door and onto the path, oral instruction is necessary.
Gong Fu (effort) is ceaseless.
Cultivate the method yourself.

Let's ask ourselves what rules work for the body (in all this):
Yi (intention) and Qi are the rulers;
Bone and flesh are the officials.

Think about it and ask yourself where the final goal lies?
It lies in the quest for longevity and the preservation of apparent youth.
It's a 140-character song.
Every character has a meaning and nothing is omitted.

If you don't question the subject in this way,
You're wasting Gong Fu (time and energy) and sighing heavily.
