Amida's life-span

Amida's life-span [12] The Buddha said to Ananda, "The life of Amitabha is so long that it is impossible for anyone to calculate it. To give an illustration, let us suppose that all the innumerable sentient beings in the worlds of the ten quarters were reborn in human form and that every one became a shravaka or pratyekabuddha. Even if they assembled in one place, concentrated their thoughts, and exercised the power of their wisdom to the utmost to reckon the length of the Buddha's life, even after a thousand million kalpas they could still not reach its limit. So it is with the life-span of shravakas, bodhisattvas, heavenly beings and human beings in his land. Similarly, it is not to be encompassed by any means of reckoning or by any metaphorical expression. Again, the number of the shravakas and bodhisattvas living there is incalculable. They are fully endowed with transcendent wisdom and free in their exercise of majestic power; they could hold the entire world in their hands."
