高僧傳 2.40

2.40

又賢在長安，大弘禪業，四方樂靖者，並聞風而至。但染學有淺深，得法有濃淡，澆偽之徒，因而詭滑。有一弟子因少觀行，自言得阿那含果，賢未即檢問，遂致流言，大被謗讟，將有不測之禍。於是徒眾或藏名潛去，或踰牆夜走，半日之中，眾散殆盡，賢乃夷然不以介意。

Moreover, while [Buddhabhadra] was in Chang'an, he greatly promoted the practice of dhyāna. Those from all directions who took pleasure in stillness heard of his renown and arrived. But their immersion in study varied in depth, and their attainment of the Dharma had degrees of richness and shallowness; frivolous and hypocritical individuals took advantage of this to be deceitful. There was a disciple who, based on a minor contemplative practice, claimed to have attained the fruit of ananāgāmin. [Buddhabhadra] did not immediately examine and question him, which led to circulating rumors. He was greatly slandered, and an unforeseen disaster was about to befall him. Thereupon his followers either concealed their names and slipped away in secret, or scaled walls and fled by night. Within half a day, the assembly was almost entirely dispersed, yet [Buddhabhadra] remained calm and untroubled.
