18.167

色界諸色，無有手足等損害等者，色界即無變壞，解色但有據方所義有增減義。

Where it says that the forms of the form realm have no damage from hands, feet, and so forth, it means that in the form realm there is no change or destruction; explaining form there only has the meaning of occupying spatial locations and the meaning of increase and decrease.
