Talmud
The Talmud records the worn out undergarments and priestly sashes were used for torch wicks in the Temple. The linen undergarments symbolized the abolition of the distinction between the heavenly and the mortal part of man, as contrasted with the divine nature, which is absolutely holy and living. According to the Talmud, the undergarments atone for the sin of sexual transgressions on the part of the Children of Israel (B.Zevachim 88b).
