Kabbalah su Proverbi 9:1

Rabbi Yehuda said, But we have already learned that the world stands upon seven pillars; (Chesed, Gevurah, Tiferet, Netzach, Hod Yesod, Malchut). As it is written, "She has hewn out her seven pillars" (Proverbs 9:1). Rabbi Yosi told him, It is certainly so! But all the other pillars stand erect because of the seventh pillar, which supports the whole world, and he is 'the righteous,' (the Yesod of Zeir Anpin). And he refreshes and replenishes the world and nourishes all (the worlds). And he is described by the verse, "Say you to the righteous, that it shall be well (also: 'that he is good') with him, for they shall eat the fruit of their doings" (Isaiah 3:10). Moreover, it is also written, "Hashem is good to all; and His tender mercies are over all his works" (Ps. 145:9).
