问：「世道日降，太古时气象如何复见得？」
先生曰：「一日便是一元[1]。人平旦时起坐，未与物接，此心清明景象，便如在伏羲时游一般。」
有人问：「世道日衰，太古时的气象如何再见到？」
先生说：「一天便是一个元气循环。人清晨起来静坐，还未与事物接触，这颗心清明的景象，便如同在伏羲时代游历一般。」
Someone asked: 'The world declines daily — how can the air of high antiquity be seen again?'
The Master said: 'A single day is one whole cosmic cycle. Rising to sit quietly at dawn, not yet in contact with things, the mind's clear brightness is like wandering in the age of Fuxi.'
- 根据邵雍的《皇极经世书》，一元为十二万九千六百年。
