Śaṅkarācārya's commentary

Stale: half-cooked. 'Yātayāma' (lit. cooked three hours ago) meaning 'powerless' is thus explained, to avoid tautology; for the next word 'gata-rasa' (tasteless) means the same, i.e., 'powerless.' Rotten: the cooked food over which one night has passed. Refuse: left after a meal. Impure: unfit for offering.
