wrong and right are two sides of the same coin
A Buddhist-influenced expression meaning that good and evil, or right and wrong, are ultimately not separate but two aspects of the same reality. Rare in everyday conversation; mostly found in philosophical or religious contexts.
The idea of 'wrong and right are but two faces of the same coin' is a profound Buddhist teaching that transcends dualistic notions of good and evil.
Also a Buddhist term expressing the non-duality of good and evil, but uses different kanji and is slightly more common in religious texts.
A four-character compound from Buddhist terminology, combining 邪 (wrong/evil), 正 (right/good), 一如 (oneness/thusness). The exact historical derivation is uncertain, but it reflects the Mahayana concept of non-duality.
