佛祖統紀 1.31

1.31

香鐙供養之具。禮誦歌唄之容。是蓋緣因加行之正轍。為但理之人。成就佛事。作法門光顯志一卷。

The implements of offerings such as incense and lamps, the deportment of bowing, chanting, and singing hymns: these are truly the correct path of conditioning causes and preliminary practices, accomplishing Buddhist activities for those who cling only to principle. I have composed the Treatise on the Glorification of the Dharma Gate in one fascicle.
