Literatura Drugiej Świątyni do Kapłańska 16:1

[56] This is why the high priest shall not enter the Holy of Holies in his robe (Lev. 16:1 ff.), but laying aside the garment of opinions and impressions of the soul, and leaving it behind for those that love outward things and value semblance above reality, shall enter naked with no coloured borders or sound of bells, to pour as a libation the blood of the soul and to offer as incense the whole mind to God our Saviour and Benefactor.

Freedom from passions (one of the meanings of “nakedness”) is illustrated by Moses setting up the Tent of Witness outside the Camp (Exod. 33:7); by Aaron entering unrobed (!) into the Holy of Holies (cf. Lev. 16:1 ff.); by Nadab and Abihu leaving their coats (or irrational parts) for Mishael and Elzaphan (Lev. 10:5); by Abraham leaving his country (Gen. 12:1); by Isaac being forbidden to go down into Egypt (i.e. the body, Gen. 26:2); and by Jacob’s smoothness (Gen. 27:11).
