About Eyes of Buddha
The Eyes of Buddha depicts two half-closed eyes. In between and slightly above the eyes is a circle or spiral which represents the urna, one of the thirty-two characteristics of a great man in Buddhism. Directly below the urna is a curly symbol styled as १, which represents the number one in Devanagari numerals. The curly symbol, which represents either a nose or a divine fire emanating from the urna above, symbolises unity.
The symbol is painted on all four sides of the cube at the top of many Tibetan-style stupas to symbolise the Buddha's wisdom seeing all things in all four cardinal directions, mostly throughout Nepal.
