The symbol depicts two half-closed eyes, a style sometimes referred to as the Adamantine View (Sanskrit: Vajradrsti).
[2] In between and slightly above the eyes is a circle or spiral which represents the urna,[3] one of the thirty-two characteristics of a great man (Sanskrit: Mahāpuruṣalakṣaṇa) in Buddhism.
[2] Directly below the urna is a curly symbol stylized as १, which represents the number one in Devanagari numerals.
[1] The Eyes of Buddha are painted[7] onto the upper portions of many Tibetan-style stupas, mostly throughout Nepal.
[11] Similar to its use on stupas, the symbol is painted on the upper portion of many caityas.
