At that time the World-Honored One, seeing that the bodhisattvas repeated their request three times and more, spoke to them, saying: "You must listen carefully and hear of the Thus Come One's secret and his transcendental powers. In all the worlds the heavenly and human beings and asuras all believe that the present Shakyamuni Buddha, after leaving the palace of the Shakyas, seated himself in the place of practice not far from the city of Gaya and there attained annuttara-samyak-sambodhi. But good men, it has been immeasurable, boundless hundreds, thousands, ten thousands, millions of nayutas of kalpas since I in fact attained Buddhahood.
"Suppose a person were to take five hundred, a thousand, ten thousand, a million nayuta asamkhya thousand-million-fold worlds and grind them to dust. Then, moving eastward, each time he passes five hundred, a thousand, ten thousand, a million nayuta asamkhya worlds he drops a particle of dust. He continues eastward in this way until he has finished dropping all the particles. Good men, what is your opinion? Can the total number of all these worlds be imagined or calculated?"
The bodhisattva Maitreya and the others said to the Buddha: "World-Honored One, these worlds are immeasurable, boundless--one cannot calculate their number, nor does the mind have the power to encompass them. Even all the voice-hearers and pratyekabuddhas with their wisdom free of outflows could not imagine or understand how many there are. Although we abide in the stage of avivartika, we cannot comprehend such a matter. World-Honored One, these worlds are immeasurable and boundless."
At that time the Buddha said to the multitude of great bodhisattvas: "Good men, now I will state this to you clearly. Suppose all these worlds, whether they received a particle of dust or not, are once more reduced to dust. Let one particle represent one kalpa. The time that has passed since I attained Buddhahood surpasses this by a hundred, a thousand, ten thousand, a million nayuta asamkhya kalpas.”
