Master Lu-Tsu said:
Your work will gradually become concentrated and mature, but before you reach the condition in which you sit like a withered tree before a cliff, there are still many possibilities of error which I would like to bring to your special attention. These conditions are recognized only when they have been personally experienced. First I would like to speak of the mistakes and then of the confirmatory signs.
When one begins to carry out one’s decision, care must be taken so that everything can proceed in a comfortable, relaxed manner. Too much must not be demanded of the heart. One must be careful that, quite automatically, heart and energy are coordinated. Only then can a state of quietness be attained. During this quiet state the right conditions and the right space must be provided. One must not sit down (to meditate) in the midst of frivolous affairs. That is to say, the mind must be free of vain preoccupations. All entanglements must be put aside; one must be detached and independent. Nor must the thoughts be concentrated upon the right procedure. This danger arises if too much trouble is taken. I do not mean that no trouble is to be taken, but the correct way lies in keeping equal distance between being and not being. If one can attain purposelessness through purpose, then the thing has been grasped. Now one can let oneself go, detached and without confusion, in an independent way. Furthermore, one must not fall victim to the ensnaring world. The ensnaring world is where the five kinds of dark demons disport themselves. This is the case, for example, when, after fixation, one has chiefly thoughts of dry wood and dead ashes, and few thoughts of the bright spring on the great earth. In this way one sinks into the world of the dark. The energy is cold there, breathing is rough, and many images of coldness and decay present themselves. If one tarries there long one enters the world of plants and stones.
Nor must a man be led astray by the ten thousand ensnarements. This happens if, after the quiet state has begun, one after another all sorts of ties suddenly appear. One wants to break through them and cannot; one follows them, and feels as if relieved by this. This means the master has become the servant. If a man tarries in this stage long he enters the world of illusory desires.
At best, one finds oneself in heaven, at the worst, among the fox-spirits. Such a fox-spirit, it is true, may be able to roam in the famous mountains enjoying the wind and the moon, the flowers and fruits, and taking his pleasure in the coral trees and jeweled grass. But after having done this, his reward is over and he is born again into the world of turmoil.
Once some hunters went deep into a dark forest and found a hut in which a hermit was praying before a wooden cross. His face shone with happiness.
“Good afternoon, Brother. May God give us a good afternoon. You look very happy.”
“I am always happy.”
“You are happy living in this lonely hut doing penance? We have everything and are not happy. Where did you find happiness?”
