[585] Which is that form that is the decay of form (rūpassa jaratā)?
That which is the aging (jarā) of form, its decrepitude, brokenness of teeth, greyness of hair, wrinkling of the skin, the dwindling of the life span, the maturing of the faculties (indriya) — this is that form that is the decay of form.
Which is that form that is not the decay of form?
The eye base (cakkhāyatana) … edible nutriment (kabaḷīkāro āhāro) — this is that form that is not the decay of form.
