Avatamsaka Sutra

The Avatamsaka Sutra (sometimes called the Flower Garland Sutra) is one of the better-known Buddhist scriptures. In the 30th chapter, the Buddha teaches a king the concept of large numbers.

The Buddha begins by calculating:

1010 * 1010 = 1020

1020 * 1020 = 1040

1040 * 1080 = 1080

1080 * 1080 = 10160

10160 * 10320 = 10320

He continues until 10101,493,392,610,318,652,755,325,638,410,240, at which he states, "that number squared is an incalculable." The Buddha that names the following:

Incalculable4 = Measureless

Measureless4 = Boundless

Boundless4 = Incomparable

Incomparable4 = Innumerable

Innumerable4 = Unaccountable

Unaccountable4 = Unthinkable

Unthinkable4 = Immeasurable

Immeasurable4 = Unspeakable

Unspeakable4 = Untold
