《吕氏春秋·纪·仲夏纪》
君子整洁身心。居处必深邃，身体要安静禁止女色，不许嫔妃进御，减少羹味，不要使它齐和，去掉一切嗜欲，安定心气，各种器官安静无为，作事不要盲动，以待确定阴阳的成败。
君子斋戒，处必揜，身欲静无躁，止声色，无或进，薄滋味，无致和，退嗜欲，定心气，百官静，事无刑，以定晏阴之所成。
A gentleman purifies his mind and body. His dwelling must be deep, his body should be quiet and he should prohibit women, not allowing concubines to come to court, reducing soup, and not making it harmonious, eliminating all addictions, stabilising his energy, various organs quiet and inactive, not acting rashly, waiting to confirm the success or failure of yin and yang.
