《幼学琼林·卷四·释道鬼神》
儒家称的 世 ，佛家称之为 劫 ，道家称之为 尘 ，这都是说还没有摆脱世俗的人事牵连；儒家说 精一 ，佛家说 三昧 ，道家说 贞一 ，这都是说深奥的道理无穷无尽。
儒家谓之世，释家谓之劫，道家谓之尘，俱谓俗缘之未脱；儒家曰精一，释家曰三昧，道家曰贞一，总言奥义之无穷。
Confucianists call it "worldly," Buddhists call it "kalpa," Taoists call it "dust," all meaning that one has not yet escaped the entanglements of worldly affairs; Confucianists say "essence-one," Buddhists say "samadhi," Taoists say "true-one," all meaning that profound principles are inexhaustible.
