In accordance with the principle that each function has a root, Abba and Imma – which are the root of Chochmah-Binah-Daat in Zeir Anpin – have their own root above. This is Chochmah S’tima’ah, which contains the root of Kindness-Judgment-Mercy, and this is what produces Abba and Imma – the general and the particular. Abba’s entire function is bound up with Kindness-Judgment-Mercy, but as one whole, whereas Imma differentiates Kindness-Judgment-Mercy into their particulars – yet Imma is still called a root. This root subsequently extends further in order to determine the governmental order of Justice in Zeir Anpin on its proper foundation by producing Zeir Anpin’s Mental Powers in him. This institutes the governmental order in its proper place with a degree of power suited to the worlds.
Wisdom of Abba of Imma
