阿彌陀經疏 1.33

1.33

佛者，夫法通四人所說，今指親從佛聞，非從弟子、諸仙、諸天化人而聞也。天竺言佛陀，此翻覺者，謂究竟覺了諸法唯只是心，如此覺了之人故號覺者。

'Buddha': now, the Dharma may generally be spoken by four kinds of persons; here it points to having heard it directly from the Buddha, not from disciples, sages, devas, or apparitional beings. In India he is called *buddha*; here translated as 'Awakened One', meaning one who has ultimately and completely awakened to the fact that all dharmas are mind alone. A person with such complete awakening is therefore titled the 'Awakened One'.
