餘百劫方修者，三無數外，餘百大劫修妙相業，諸佛因中法應如是。唯釋迦佛精進熾然，能超九劫，九十一劫修妙相成也。

'Cultivated only in the remaining hundred eons': Beyond the three incalculables, in the remaining one hundred great eons one cultivates the karma of the wondrous marks; such is the regular principle for all Buddhas on the causal path. Only Śākyamuni Buddha, with blazing vigor, was able to surpass nine eons, completing the cultivation of the wondrous marks in ninety-one eons.
