And these are called the two states of greatness, the first and the second. The first is when it receives from Israel-Saba and Tevunah. The second is when it receives from Abba and Imma without the aforementioned division, which is a power far greater.
Zeir Anpin in Zion
Kalach Pitchei Chokhmah 129:4
וְאֵלּוּ נִקְרָאִים שְׁנֵי גַּדְלוּת - רִאשׁוֹנָה וּשְׁנִיָּה, רִאשׁוֹנָה - כְּשֶׁמְּקַבֵּל מִיסוּ"ת. שְׁנִיָּה - כְּשֶׁמְּקַבֵּל מֵאו"א בְּלֹא הִתְחַלְּקוּת הַנַּ"ל, שֶׁהוּא כֹּחַ יוֹתֵר גָּדוֹל הַרְבֵּה.
