Kabbalah su Cantico dei cantici 8:8

It is written, “Say to wisdom, You are my sister” (Mishlei 7:4). There is Chochmah, and then there is Chochmah. That is, upper Chochmah that is Aba and Ima and lower Chochmah that is Malchut. This Female, which is Malchut, is called the lesser Chochmah in relation to the other, which is the highest Chochmah. It is therefore written, “We have a little sister, and she has no breasts” (Shir Hashirim 8:8). This Chochmah was carried into exile and therefore has no breasts to extend abundance to Israel. “We have a little sister”: she surely seems little while in exile; but she is great and multitudinous, being the wholeness that receives from all the Sfirot, when Israel dwell in their own land, as written, “I was a wall, and my breasts were like towers” (Ibid. 10), that is, they are full to suckle everyone. They are as towers that are the great rivers that originate in the highest Ima that are called towers.
