Tehillim 51:15 Kabbala: Reshit Chokhmah

I also heard regarding the correction of the sign of the Brit that one should make an effort to inspire others to do Teshuva, corresponding to that which he emitted semen outward, and every drop is a soul that is captive in the hands of the External Forces, and therefore corresponding to this he should make an effort to take people that are controlled by the External Forces out of there and bring them into the Holiness. As King David said, “Then will I teach transgressors Your ways; and sinners shall return unto You” (Psalms 51:15), and it is known that Tzadik is called ‘tongue of the learned’, as is explained in the portion of Pinchas.
