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 * 1040 = 1080
• 1080 * 1080 = 10160
• 10160 * 10160 = 10320
• ...

He continues until 10101,493,392,610,318,652,755,325,638,410,240 or 101.015*1032, at which he states, "that number squared is an incalculable." (which is 10202,986,585,220,637,305,510,651,276,820,480 or approximately 102.03*1032) The Buddha then names the following:

• Incalculable4 = Measureless (~ 108.12*1032)
• Measureless4 = Boundless (~ 103.25*1033)
• Boundless4 = Incomparable (~ 101.3*1034)
• Incomparable4 = Innumerable (~ 105.2*1034)
• Innumerable4 = Unaccountable (~ 102.04*1035)
• Unaccountable4 = Unthinkable (~ 108.16*1035)
• Unthinkable4 = Immeasurable(~ 103.26*1036)
• Immeasurable4 = Unspeakable (~ 101.3*1037)
• Unspeakable4 = Untold (~ 105.2*1037)

The "Untold" number is much larger than googol or guppyplex, but still smaller than googolplex.

In other version of the Chinese translation of this script (note that only the translation remains in present), the largest number is Nirabhilapya nirabhilapya parivarta (Bukeshuo bukeshuo zhuan 不可說不可說轉) the largest number which is equal to $$10^{7 \times 2^{122}}$$.
