חסידות אויף ישעיהו 41:4

This is the meaning of the verse,²Isaiah 41:4 “He calls out the generations from the beginning (Rosh-ראש),” that is, from the “head (Rosh-ראש)” of Adam Kadmon etc.

This is because although the aspect of the vessels, which limit the external emotions of the heart of Zeir Anpin, are [in the aspect of] ultimate “smallness” compared to the exaltedness of the essential emotions of the aspect of Malchut of the Unlimited One – Ein Sof, they nevertheless are considered to be the aspect of the end of the beginning, as scripture states, “He calls out the generations from the beginning etc.”⁴Isaiah 41:4
