Salmi 25:14 Cabala: Or Neerav, Zohar, Reshit Chokhmah & Idra Zuta

Rabbi Abba arose and said “If it pleases you, sir, [to reveal this matter] it is written, The secret of the Lord is to those who fear Him (Ps. 25:14). Now the colleagues do fear the Holy One, blessed be He. They have already entered the ‘idra concerning the Tabernacle.⁶Zohar II, 127a-146a. Some entered and some left.”

He who reveals to them the secrets of the Torah causes the departure of the flow [of emanation] from the righteous Yesod, of whom it is said, The secret of the Lord is for those who fear Him (Ps. 25:14), and from the Shekhinah, as it is written, The water left the sea, and the river is dry and parched (Job. 14:11). At that time, the righteous below are entirely impoverished: bereft of the mysteries of Torah and poor in their bodies.

All this teaches that the mysteries of the Torah abide in Yesod. Thus [the sefirah] is called Yesod, [a combination of] the yod of the covenant and mystery [sod], which is the mystery of the Torah. Proof for this is [derived from the verse], The secret of the Lord is for those who fear Him; and His covenant to make them know it (Ps. 25:14). Thus “covenant” and “mystery” are as one. All this demonstrates that when mysteries [of the Torah] are spread among the “outside” ones, they are removed from the “inner” ones.
