Sexuality

You can profoundly rectify your mis-spent sexuality by sanctifying your will and illuminating it clearly, until the light of holiness will stream through even your strongest physical drive. That drive is rooted in holiness that is incredibly strong, because it contains the expression of life: the sexual drive. The light of holiness will stream within it to such a degree that its holy aspect will rule your life and direct its action and expression. Then sexuality's secular aspect, and certainly its unclean aspect, will be totally nullified before its holy aspect. Then, in truth, the plague will not enter your tent; you shall be righteous and guarded from stumbling.

Orot Hakodesh III, p. 298

The sexual drive streams into the future, to the perfection of life that time will bring: the life of the world-to-come within this world. That future life is filled with complete beauty and pleasure; thus, great is the yearning and the strength of desire of the sexual drive, which is all-encompassing; only upon this drive does ultimate holiness rest its light. The pure soul leads the sexual drive to its goal within the boundary of Torah, wisdom, rectitude and modesty: the sources of righteousness.

Orot Hakodesh III, p. 296

The precious reason for circumcision, which decreases sexual desire, encompasses broad principles of wisdom. The covenant—"to be a God to you and to your children after you"—offers knowledge of God's oneness, which is connected to circumcision. The covenant and circumcision are intimately intertwined. "From his flesh does a man see God."
