「大哉乾元,萬物資始,乃統天。雲行雨施,品物流形,大明終始,六位時成,時乘六龍以御天。乾道變化,各正性命,保合大和,乃利貞。首出庶物,萬國咸寧。」〈彖傳〉 「天行健,君子以自強不息。」〈象傳〉 「天尊地卑,乾坤定矣。卑高以陳,貴賤位矣。動靜有常,剛柔斷矣。方以類聚,物以羣分,吉凶生矣。在天成象,在地成形,變化見矣。」〈繫辭傳〉 「天地定位,山澤通氣,雷風相薄,水火不相射。八卦相錯,數往者順,知來者逆。是故易逆數也。」〈說卦傳〉 「有天地,然后萬物生焉。盈天地之間者,唯萬物,故受之以屯;屯者盈也,屯者物之始生也。」〈序卦傳〉 「乾剛,坤柔,比樂師憂。臨觀之義,或與或求。屯見而不失其居,蒙雜而著。震,起也,艮,止也。損、益,盛衰之始也。」〈雜卦傳〉 「元者,善之長也;亨者,嘉之會也;利者,義之和也;貞者,事之幹也。君子體仁足以長人,嘉會足以合禮,利物足以和義,貞固足以幹事。君子行此四德者,故曰乾、元、亨、利、貞。」〈文言傳〉
