大方廣圓覺修多羅了義經略疏 2.1192

2.1192

去其久近，無別所表。方等經極少七日，久則不遮。次下正明法事，準《離垢慧菩薩所問禮佛法經》，總有八重：一供養、二讚佛、三禮佛、四懺悔、五勸請、六隨喜、七迴向、八發願。今略唯二，謂禮佛、懺悔。然文雖略，法必具行。《論》中亦云：「應當精勤禮佛、懺悔、勸請、隨喜、迴向，常不休息，得免諸障，善根增長。」《華嚴》亦令禮敬、稱讚、供養、懺悔等。

Setting aside its length or brevity, there is no special symbolism. In the Vaipulya sūtras, the minimum is seven days; longer periods are not prohibited. Next below, the ritual practice is formally clarified. According to the Sūtra on the Method of Worshipping the Buddha Spoken to Vimalaprabhāmati Bodhisattva, there are eight layers in total: 1. making offerings, 2. praising the Buddha, 3. prostrating to the Buddha, 4. repentance, 5. entreaty, 6. rejoicing, 7. dedication of merit, and 8. generating vows. Here it is abbreviated to only two: worshipping the Buddha and repentance. Yet although the text is brief, the practice must be performed completely. The Treatise also states: "One should diligently worship the Buddha, repent, entreat, rejoice, and dedicate merit, constantly without rest; one will thereby escape all obstacles and one's roots of goodness will increase." The Huayan also enjoins paying homage, praising, offering, repenting, and so forth.
