The Buddha shares a simile of a mountain to illustrate the inevitability of old age and death, and the importance of living by the Dhamma.

The Buddha explains the vastness of an aeon using a simile of wiping a mountain with a piece of fine cloth.

When five hundred bhikkhus headed by the venerable Yasoja come to see the Buddha, they make a great commotion while preparing their lodgings. The Buddha dismisses them out of compassion, and later, they so dwell that the Buddha may be pleased with them. Living secluded, diligent, resolute, and with continuous effort, they all realize the three true knowledges during that very rainy season.
