"During the sleep of his guest, Lang-Ho took off his robe, replacing it by a garment made of two materials. One was golden yellow, the other a brilliant green. After attacks of terrible anger, in spite of the solicitation of his impulsive nature which incited him to go out, he did not dare to venture into the streets in such a costume. "That which the most subtle arguments had been unable to accomplish, was obtained through fear of ridicule. "Two days passed; his fury was changed into great mental exhaustion, because impulsive people can not withstand the contact with obstacles for any length of time. "It was this moment which my master chose to undertake the cure, in which he was so vitally interested. "With the most delicate art, he explained to the impulsive man all the chain of sentiments leading from perception to judgment. "He caused common sense to intervene so happily that the man was permeated by it. My master kept him near by for several weeks, always using very simple arguments to combat the instinctive resolutions which were formulated in his brain many times a day. "Common sense, thus solicited, was revealed to the impulsive one, and appeared like a peaceful counselor. "The ridiculous and odious side of his resolution was represented to him with such truth that he embraced Lang-Ho, saying: "'Now, Master, I can go away, and your mind can be at rest about me. "'The arguments of common sense have liberated me from bondage in which my lack of reflection held me. "'I return to my home, but, I beg of you, allow me to take away this ridiculous costume which was my savior. "'I wish to hang it in my home, in the most conspicuous place, that, from the moment my nature incites me to obey the commands of impulse, I may be able to look at once upon this garment, and thus recall your teachings, which have brought sweetness and peace into my life.'" All those who are inclined to act by instinct should follow this example, not by dressing up in a ridiculous robe half green and half yellow, but by placing obstacles in the way of the accomplishment of impulsive acts, which the dictates of common sense would not sanction. "For those whose mind possess a certain delicacy," again says the old master, "these obstacles will be of a purely moral order, but for those who voluntarily allow themselves to be dominated by a diseased desire for action, obstacles should adopt a tangible form; the difficulty in conquering anything always makes impulsive people reflect a little. "Under the immediate impression of the perception of an act they are ready for a struggle to the death; but this ardor is quickly extinguished, and inertia, in its turn, having become an impulse, makes them throw far away from them the object which determined the effort. "In proportion as they encounter obstacles, which they have taken the precaution to raise, the encroachment of the impression will make itself less felt.
