From 《
论语·
里仁》 (Analects, Book 4): Confucius said
参乎!
吾道一以贯之 — 'Shen! My Way is threaded through by a single principle.' When asked by others, Zengzi (
曾子) explained it as
夫子之道,
忠恕而已矣 ('the Master's Way is nothing but loyalty and empathy'). One of the most important hermeneutic keys to the Analects.
