大般涅槃經集解 71.60

71.60

案僧亮曰：弘廣晦迹，引諸無知應弘此經。時將顯迹，現所聞不遠也。寶亮曰：更無所執，直作心念試佛。佛即知其所念，復過己心所見，於是即伏。故憍陳如先難己所為，佛即顯其迹也。

Sengliang comments: Hongguang concealed his traces to guide the ignorant, in order to propagate this sūtra. As the time approached to reveal his traces, he showed that what he heard was not from far away. Baoliang comments: Having no further attachments, he simply formed a thought in his mind to test the Buddha. The Buddha immediately knew what he was thinking, which surpassed what his own mind had seen; thereupon he submitted. Thus Kauṇḍinya first challenged what he did, and the Buddha immediately revealed his traces.
