उच्छ्वासितप्रस्थसंधयः यस्य सः
बहुव्रीहि — the mountain whose seams they are
बहुव्रीहि — it refers to कैलासस्य. whose plateau-seams were sprung apart by the ten-faced one's arms — Rāvaṇa, who put his shoulder under Kailāsa and lifted. Mallinātha builds it member by member and glosses the two that are not obvious: दशमुखस्य रावणस्य, so the ten faces are the name and not a description; and उच्छ्वासिताः विश्लेषिताः, 'made to breathe out, that is, made to come apart'. उच्छ्वासित is the causative participle of उद् + √श्वस्, to breathe up, so a mountain's joints loosening is described as a body exhaling. **Then he says what the compound is for**: एतेन नयनकौतुकसद्भाव उक्तः, 'by this the existence of something worth the eye's curiosity is stated'. It is not scene-setting. The cloud is being given a reason to stop, and the reason is that there is damage to look at
uncheckedMallinātha, Sañjīvinī, who names Rāvaṇa, glosses उच्छ्वासित with विश्लेषित and says what the compound establishes. `vendor/meghaduta-sanjivini.itx` prints `sa~Nghayo` for `संधयः`, which is read through against the word being glossed“daśamukhasya rāvaṇasya bhujairbāhubhirucchvāsitā viśleṣitāḥ prasthānāṃ sānūnāṃ saṃdhayo yasya tasya || etena nayanakautukasadbhāva uktaḥ”
