Kabbalah Mazmur 37:21: Sha'arei Orah

Now, throughout the Torah this quality is called The Righteous One-Tzaddik-צדיק. Moreover, because it is called the Foundation-Yesod-יסוד and carries all entities that are below it, it is called,³⁰Proverbs 10:25 “the Righteous One-Tzaddik-צדיק, the Foundation-Yesod-יסוד of the world.” The reason it is called Righteous-Tzaddik-צדיק is because it influences all goodness and blessings into HaShem’s-יהו"ה quality of Lordship-Adona”y-אדנ"י, as it states,³¹Psalms 37:21 “the righteous-Tzaddik-צדיק is generous and gives.”
