This Atika, Arich Anpin, the most primordial – Supernal Aba and Ima that are called old stem from it – is the supernal Keter on high, that is, Keter of Arich Anpin. Every crown is crowned with it, that is, every brain. All brain lobes are called crowns, being the seven perfections of the head that shall be explained soon and the thirteen features of the beard. Crowns – Aba and Ima – shine from it, and all the other candles, the seven lower Sefirot that contain Judgments are alight with it and shine. Nevertheless, it itself is a supernal concealed and unknown candle.
