Kalpa of formation

(tib.: chak pe kal pa) According to Abhidharmakosha, the power of the karma of living beings first causes a small wind to arise in space. This wind grows and forms the windy circle thought to lie at the base of a world. Upon this windy circle, a watery circle and then a gold circle take shape, and upon them forms the land, with a Mount Sumeru, seas, and mountains. Then living beings begin to appear, first in the heavens, then in the human world, and successively in the lower of the six worlds, until finally beings appear in the hells. Human lives are immeasurable (a specific number with > 30 zeros) at this point. The formation eon ends when the first being is born in Avichi hell. Lifespans have dropped to 80,000 years at that point.
