藥師經疏 1.69

1.69

經。阿難至亦不究盡　六劫窮盡讚舉藥師如來利他行願說難可盡勸物定信。無量菩薩行者。謂彼如來本昔行無量利他菩薩行。無量諸巧便者。謂今得佛已後。以無量後得慈悲方便利益三乘。無量曠大願者。謂彼如來非唯有十二大願。乃有無量曠大願利益眾生故應專信。

Sūtra: 'Ānanda... could not be exhausted.' Section 6: Praising that an eon could be exhausted. It adduces that the altruistic practices and vows of Bhaiṣajyaguru Tathāgata are difficult to exhaustively state, urging beings to have firm faith. 'Immeasurable bodhisattva practices' means that this Tathāgata originally practiced immeasurable altruistic bodhisattva practices in the past. 'Immeasurable skillful means' means that now, after attaining buddhahood, he uses immeasurable subsequent compassion and skillful means to benefit the three vehicles. 'Immeasurable vast vows' means that this Tathāgata has not only twelve great vows, but immeasurable vast vows to benefit sentient beings; therefore, one should exclusively have faith.
