सुरभिताः शिलाः
कर्मधारय — rocks that have been made fragrant
सुरभिताः शिलाः यस्य तम्
बहुव्रीहि — the mountain whose rocks they are
बहुव्रीहि — it refers to अचलम्. whose rocks are made fragrant — Mallinātha carries the whole bahuvrīhi over in one breath, तासां गन्धैः सुरभिताः सुरभीकृताः शिला यस्य तम्, 'the one whose rocks are made fragrant by their scents'. His gloss सुरभीकृताः is the point: सुरभित is not 'fragrant' but 'made fragrant', a participle built on सुरभि by the च्वि-and-causative route that turns a quality into something done to a thing. The rocks did not smell of musk until the deer lay on them
