The Arcs of Descent and Ascent (Arabic: قوس النزول وقوس الصعود), an ontological circle, are described in Neoplatonism, as well as in Islamic and Sufi cosmology, mainly inspired by the works of Ibn al-Arabi. In the Arc of Descent ("qaws al-nuzuli"), from unity to diversity, God creates successively the Intellect (Supreme Pen), the Universal Soul (Guarded Tablet), Prime Matter, Nature, the Universal Body (including the imaginal world) and the Earth. The Arc of Ascent ("qaws al-su'ud") is the way back to the Presence of God, the process of spiritual perfection.[1][2]
In a hadith attributed to Ja'far al-Sadiq, the sixth Imam of Shi'i Islam, the arc of descent is described as having seven stages. These stages have been commented on in Shaykhism.[3]
