he replied.  “What way, and where is it?” they asked.  He pointed to the sky.  “Where is the sky?” they went on.  He pointed to his heart.  The two visitors smiled and said:  “The heart is the sky, and the sky is the Way; you understand the origin of things.”  They then gave him a recipe for perfection, to enable him to take his place among the Perfect Ones.  In a few days only he had reached this much-sought-after condition.

In another version we find fuller details concerning this Immortal.  A graduate named Yuean Wen-cheng of Ch’ao-yang Hsien, in the sub-prefecture of Ch’ao-chou Fu in Kuangtung, was travelling with his wife to take his examinations at the capital.  Ts’ao Ching-chih, the younger brother of the Empress, saw the lady, and was struck with her beauty.  In order to gratify his passion he invited the graduate and his young wife to the palace, where he strangled the husband and tried to force the wife to cohabit with him.  She refused obstinately, and as a last resort he had her imprisoned in a noisome dungeon.  The soul of the graduate appeared to the imperial Censor Pao Lao-yeh, and begged him to exact vengeance for the execrable crime.  The elder brother, Ching-hsiu, seeing the case put in the hands of the upright Pao Lao-yeh, and knowing his brother to be guilty of homicide, advised him to put the woman to death, in order to cut off all sources of information and so to prevent further proceedings.  The young voluptuary thereupon caused the woman to be thrown down a deep well, but the star T’ai-po Chin-hsing, in the form of an old man, drew her out again.  While making her escape, she met on the road an official procession which she mistook for that of Pao Lao-yeh, and, going up to the sedan chair, made her accusation.  This official was no other than the elder brother of the murderer.  Ching-hsiu, terrified, dared not refuse to accept the charge, but on the pretext that the woman had not placed herself respectfully by the side of the official chair, and thus had not left a way clear for the passage of his retinue, he had her beaten with iron-spiked whips, and she was cast away for dead in a neighbouring lane.  This time also she revived, and ran to inform Pao Lao-yeh.  The latter immediately had Ts’ao Ching-hsiu arrested, cangued, and fettered.  Without loss of time he wrote an invitation to the second brother, Ts’ao Ching-chih, and on his arrival confronted him with the graduate’s wife, who accused him to his face.  Pao Lao-yeh had him put in a pit, and remained deaf to all entreaties of the Emperor and Empress on his behalf.  A few days later the murderer was taken to the place of execution, and his head rolled in the dust.  The problem now was how to get Ts’ao Ching-hsiu out of the hands of the terrible Censor.  The Emperor Jen Tsung, to please the Empress, had a universal amnesty proclaimed throughout the Empire, under which all prisoners were set free.  On receipt of this edict, Pao Lao-yeh liberated Ts’ao Ching-hsiu from the cangue, and allowed him to go free.  As one risen from the dead, he gave himself up to the practice of perfection, became a hermit, and, through the instruction of the Perfect Ones, became one of the Eight Immortals.
