6.192

此中備師解云：要待善知識種解脫分善，今佛及弟子名善知識。又若准善生經，由值佛及阿伽膩宅天，殖勝脫分，即第十地菩薩名攝報處故。

Here Master Bei explains: 'One must rely on good spiritual friends to plant the wholesome roots of the aids to liberation; here, the Buddha and disciples are called good spiritual friends. Furthermore, according to the Sujāta-sūtra, by encountering the Buddha and the Akaniṣṭha heaven, one plants the superior aids to liberation, because the tenth-stage bodhisattva is called the realm of gathered retribution.'
