*Buddhapashcimavavadopadesha 1.40

1.40

經曰：汝等比丘！若求寂靜無為安樂，當離憒鬧獨處閑居。靜處之人，帝釋諸天所共敬重，是故當捨己眾他眾，空閑獨處思滅苦本。若樂眾者則受眾惱。譬如大樹眾鳥集之，則有枯折之患。世間縛著沒於眾苦，如老象溺泥不能自出。是為遠離。

The sūtra says: 'You bhikṣus! If you seek the peaceful joy of unconditioned quietude, you should leave turmoil and dwell alone in solitude. A person in a quiet place is reverenced together by Śakra and all the devas. Therefore, you should abandon your own group and other groups, dwelling alone in a quiet and empty place to contemplate the extinguishing of the root of suffering. If you take delight in a group, you will receive group distress. It is like a great tree where many birds flock: it has the calamity of drying up and breaking. Attachment to the world submerges one in many sufferings, like an old elephant stuck in the mud, unable to get out on its own. This is retirement.'
