The Abhidharmakośa states: The three small calamities all arise when the lifespan is ten years, and therefore occur in separate kalpas. Now, the Mahāyāna holds that they arise within the same kalpa at thirty, twenty, and ten years of age: famine, disease, and warfare respectively. As the Abhidharmakośa states, famine has three aspects: first, white bones; second, moving tallies; and third, gathering. It is as broadly explained therein.
