首楞嚴義疏注經 6.396

6.396

絲綿、裘毳，眾生身分，身既不服，真解脫者，以不遊三界詶宿債故。經語甚倒，知之。

Silk, floss, furs, and down are parts of the bodies of living beings. Since the body does not wear them, they are truly liberated because they do not wander through the three realms to repay past debts. The phrasing of the sūtra is quite inverted; take note of this.
