Asaṃkhyeya
An  () is a Buddhist name for the number 10140, or alternatively for the number  as it is described in the Avatamsaka Sutra. The value of the number is different depending upon the translation. It is  in the translation of Buddhabhadra,  in that of Shikshananda and  in that of Thomas Cleary, who may have made an error in calculation. In these religious traditions, the word has the meaning of 'incalculable'. Asaṃkhyeya is a Sanskrit word that appears often in the Buddhist texts. For example, Shakyamuni Buddha is said to have practiced for 4 great asaṃkhyeya kalpas before becoming a Buddha. See also
