On one occasion the Blessed One was staying near Savatthi in Jeta's Grove, Anathapindika's monastery. Then two brahmans — feeble old men, aged, advanced in years, having come to the last stage of life, 120 years old — went to the Blessed One. On arrival, they exchanged courteous greetings with him and, after an exchange of friendly greetings & courtesies, sat to one side. As they were sitting there, they said to him: "Master Gotama, we are brahmans — feeble old men, aged, advanced in years, having come to the last stage of life, 120 years old. And we have done no admirable deeds, no skillful deeds, no deeds that allay our fears. Teach us, Master Gotama. Instruct us, Master Gotama, for our long-term benefit & happiness."

"Indeed, brahmans, you are feeble old men, aged, advanced in years, having come to the last stage of life, 120 years old. And you have done no admirable deeds, no skillful deeds, no deeds that allay your fears. This world is on fire with aging, illness, & death. With the world thus on fire with aging, illness, & death, any restraint of body, speech, & intellect practiced here will be one's shelter, cave, island, & refuge after death in the world beyond."
