凡佛教之經典有五人之說者,佛說其一也。佛說者,佛之金口自宣說法也。法華經藥草喻品曰:「如來是諸法之王,若有所說皆不虛也。」
Buddha's preaching; the Buddha said. Buddha's utterance of the sutras. There are over 150 sutras of which the titles begin with these two words, e.g. 佛說無量壽經 Aparimitāyus Sutra, tr. by Saṇghavarman A.D. 252.
一佛說 佛以金口自宣說法。為顯金口之法,以別於三乘、天、人之說,諸經卷首多置此二字,藉以證明佛所說法乃真實之教。又菩薩之法,若受佛之印可,亦視同佛說。〔大智度論卷二、金剛般若疏卷一〕p3439
