Come see: Of everyone who guards the sign of the covenant, his image is inscribed in the Shekhinah (Malkhut) and ‘the Righteous-One’ (Yesod), and yet of one who strives in the Torah, his image is inscribed in ‘the Middle Pillar’ (Tipheret).
Be-REiShYT It is written: (Ps. 118:19) Open for me the gates of righteousness, I shall enter through them, I shall acknowledge Y-Q. Open for me... – these are the two eyelids, which open and shut, and about them it is stated: (Ex. 25:20) And the cherubs shall be spreading their wings upwards... [cherubs] – these are the two cherubs of the eyes, spreading wings – the eyelids.
