大方廣佛華嚴經隨疏演義鈔 29.15

29.15

疏「更有四方如十定品」者，即第四十二阿耨達池喻中合池四方，云「佛子！何者名為菩薩四方？所謂見一切佛而得開悟（一）；聞一切法受持不忘（二）；圓滿一切波羅蜜行（三）；大悲說法滿足眾生（四）。」釋曰：若觀此四，為菩薩道也。

Regarding the Commentary: "There are also four directions as in the 'Chapter on the Ten Samādhis'," this is in the forty-second [fascicle], where the metaphor of Lake Anavatapta matches the four directions of the lake, saying: "O sons of the Buddha! What are the four directions of a bodhisattva? They are: seeing all Buddhas and attaining awakening (1); hearing all dharmas and retaining them without forgetting (2); fulfilling all practices of the pāramitās (3); and preaching the Dharma with great compassion to satisfy sentient beings (4)." The explanation says: if one contemplates these four, this constitutes the path of the bodhisattva.
