that. For the human being is composed of limbs and joints, and there is no limb or joint except that it manifests to him as a Personification (Shakhs) whose gnosis is obligatory upon him.

"I said: 'My Master, favor me with that so that I may know it.'

He, Mighty is His Might, replied: 'As for the beginning of that: the Son of Adam was created upon Four Temperaments (Taba'i'): Dryness, Moisture, Heat, and Cold; and his composition was constructed upon the image of the Firmament (Surat al-Falak).

As for Dryness: it corresponds to the station of Abu al-Dharr.
