佛說處處經 1.16

1.16

「佛說八十億萬因緣經，都治人三病：一者、貪婬；二者、瞋恚；三者、愚癡。是三事分為六，故應六衰治三病。經所以多者，譬如人服藥病不愈，當更服餘藥。佛言：『人意多端，疾轉故多經，隨意療，之欲使疾解故。』

"The eight hundred million nidāna sūtras spoken by the Buddha all cure people's three afflictions: first, lust; second, ill-will; third, delusion. These three matters are divided into six; thus they correspond to the six defilements to cure the three afflictions. The reason the sūtras are so numerous is that, just as when a person takes medicine and the illness is not cured, he must take another medicine. The Buddha said: 'People's minds have many inclinations and shift swiftly; therefore the sūtras are many. They are cured according to their inclinations, wishing to cause them to understand quickly.'"
