“Therefore, the length of the great being’s
Lifespan cannot be calculated
By saying it is a certain number of eons,
Or likewise by saying it is countless eons.⁶¹

“Therefore, do not doubt, do not have any doubt whatsoever.
No one can conceive of the final extent of a jina’s lifespan.”

Then the bodhisattva Ruciraketu, having heard that teaching on the lifespan of Bhagavat Śākyamuni, asked those bhagavats, “Why is it that the Bhagavat Śākyamuni, the Tathāgata, manifests such a short lifespan?”

The bhagavats said to the bodhisattva Ruciraketu, “The Bhagavat Śākyamuni, the Tathāgata, has been born at a time when beings could live for a hundred years in a world that has the five degenerations. Therefore, the Tathāgata Śākyamuni has manifested a short lifespan in order to benefit beings with inferior aspiration, beings with little roots of merit and faith, and ordinary foolish beings who have the view that there is a being, the view that there is a soul, the view that there is a spirit, the view that there is an individual, erroneous views, the belief in ‘me’ and ‘mine,’ the views of eternalism and nihilism, and so on. It is also to inspire the true view in tīrthikas so that they will quickly attain the highest enlightenment.

“Moreover, noble one, the Tathāgata, by manifesting passing into nirvāṇa, causes beings to perceive him as rare and difficult to meet; causes them to perceive misery, suffering, and so on; and inspires them to quickly obtain, possess, read, comprehend, and teach widely to others these sūtras that have been taught by the Buddha Bhagavat, and to not malign them.
