"Understanding life" is different from merely "accepting life." Accepting life can be pessimistic, a giving up of life. Understanding life is to understand that all things exist through causes and conditions. Whatever is supposed to come, favorable or adverse, it will come. 「知命」與「認命」不同。「認命」是消極的態度， 完全放棄生命的作為；「知命」則是認知萬事萬物有 其因緣，該來的總是會來，順逆皆然。- Master Sheng Yen
