佛祖統紀 3.55

3.55

時長通後。述曰。評時長通至三處者。謂般若海空法華佛慧涅槃心地法門是也。妙玄引無量義經云。次說般若歷劫修行華嚴海空。法華會入佛慧。即是通至二經（籤云。以般若亦得名華嚴。法華佛慧不殊初故。又妙樂云。當知法界論之無非華嚴。佛慧言之無非法華）。

Prolonged duration extending to what follows. The commentary states: In evaluating prolonged duration extending to three places, it refers to the Prajñā's ocean of emptiness, the Lotus's Buddha-wisdom, and the Nirvāṇa's mind-ground Dharma-gate. The Miaoxuan cites the Wuliangyi jing, saying: 'Next he preached Prajñā, practicing for kalpas, the Avataṃsaka's ocean of emptiness; the Lotus converges into Buddha-wisdom'—that is, it extends to these two sūtras. (The Qian states: 'Because Prajñā can also be named Avataṃsaka, and the Lotus's Buddha-wisdom is not different from the beginning. Furthermore, the Miaole states: One should know that in discussing the Dharma realm, there is none that is not the Avataṃsaka; in speaking of Buddha-wisdom, there is none that is not the Lotus.')
