And beneath it there was a treasure belonging to them, that is, the treasure of gnosis which is only actualised through these two [faculties] at the station of the heart on account of the fact that all of the universals and the particulars are able to come together in it [the heart] in actuality at the moment of perfection, which is the state of coming of age and the extraction of that treasure. Some exoteric commentators relate that the treasure was scrolls in which there was [certain] knowledge. Their father had been - [this is valid] in the case of both interpretations - a righteous man: it is also said that he was a father from 'above' to them and God preserved them for him, in which case, he can only be the holy spirit.
The story of DhūÌl-Qarnayn is well-known. He was a Greek (rūmī) who lived in times not long ago.
