Three Clarities (三明). An Arhat has achieved
(1) clear knowledge of the past lives of self and others and their causes and conditions,
(2) clarity of his god-eye that sees others’ future lives and their causes and conditions, and
(3) clear knowledge that his afflictions have ceased and will never arise again.
The Three Clarities of a Buddha are supreme and are called the Three Supreme Clarities (三達).
