Adhyātma–Adhibhūta–Adhidaivata Correspondences and the Triguṇa Lakṣaṇas (Śānti-parva 301)
शिराशतसमाकीर्णे नवद्वारे पुरेडशुचौ । विज्ञाय हितमात्मानं योगांश्व विविधान् नूप

毗湿摩说道：“在这不净之城（此身）中，遍布数百脉道，具九门；人当认知自我（Ātman）乃自身至上之利。既明了有身之境——众生不得不居于不净与苦恼之中——大王啊，当学习经典所教的种种瑜伽修持；由此证得自我，成就真实安乐。”

Educational Q&A
The body is an impure, perishable dwelling with many channels and nine openings; knowing this, one should treat realization of the Self (ātman) as the highest welfare and pursue the scripturally taught yogic disciplines that lead to liberation.
Bhishma is instructing the king in Shanti Parva, using the metaphor of the body as a 'city with nine gates' to cultivate dispassion and to direct the listener toward learning and practicing yoga for Self-realization.
