186 " the mosque" Is understood the power of remem- bering and praising God; by " one's Imam/' medi- tation; and " the angels" mean the powers of the inmost soul, such as abstraction, memory, praise of God, and the like. Further," saluting them" refers to the comprehending of all the mental powers. Thus, when one wishes to mount up to the terrace of a house, he must first have a staircase by which he may, step after step, ascend, until he attains the summit of the terrace; in like manner also are these refined powers to be considered as ladder- steps, upon which, the one after the other, a man ascends until he arrives at his aim. " And what the prophet said: When I became 44 free, I raised my face upwards, and I found a 46 ladder, one step of which was of silver and the 44 other of gold:"i this means, from the external to the internal sense; ^gold" and '" silver" denote the superior value of the one over the other.2 1 From the temple, the prophet was conducted by Jabrill to the rock upon which Abraham was ready to sacrifice his son Isaac. From them rose a ladder to heaven; not only were the steps alternately of gold and silver, but also, on one side shone edifices of emerald, and on the other palaces of ruby. 2 Here Jabriil took Muhammed upon his wings and flew with him to the gate of Paradise, which was guarded by a legion of Angels. In the first heaven he saluted Adam, who sat between two gates, and was look- ing now to the right, now to the left; when to the right, he laughed, when to the left, he wept; for the right hand led to heaven, the left to hell: the first father's joy or sadness followed his children going to either side.
