“The letter nun in Arabic (ن) resembles an ink-pot which ‘contains’ the ink with which the archetypes of all beings are written upon the Guarded Tablet. This letter also resembles a ship which carries the possibilities of a particular cycle of manifestation upon the ‘ocean of non-existence’. The fifteenth century Persian Sufi scholar Kamal al-Din Husayn Kashifi, in his Quranic commentary, relates the letter nun to the first letter of light (al-nur) which was the first reality created by God according to the narration, ‘the first thing that God created was light’, and the last letter of al-Rahman, the Divine Mercy, by virtue of which all creation was brought forth.”
