"Granary" (kuśūla) is a storehouse; "jar" (kumbhī) is a small earthen pot. "Kuśūlakumbhyau" means a granary and a jar; one whose grain is measured by those is so called: he may be one with grain in a granary, or one with grain in a jar. Among them, one who has grain sufficient only for twelve days to sustain his own household is "one with grain in a granary". But "one with grain in a jar" has grain sufficient only for six days to sustain his own household. "Having for three days" means he has grain sufficient for three days. "Having for the morrow" means he has grain pertaining to tomorrow; one who has nothing for tomorrow is "having none for the morrow" (aśvastana).
