Vishnu prostrates before Bhairava — Shiva Purana 3.9.6-7

The scene is doing something specific with rank. Bhairava arrives mid-penance, carrying a skull, outside every category of purity, and Vishnu falls daṇḍavat — flat, like a felled staff, the fullest prostration there is — and the assembled gods and sages go down with him. pūrṇākāraṃ, 'in his complete form', is the phrase that carries the argument. It is the same claim the Ashta Bhairava Dhyana Stotram opens with — bhairavaḥ pūrṇarūpo hi śaṅkarasya parātmanaḥ — and the same claim this Purana made back in 3.8.2. Bhairava is not a fragment of Shiva shown in anger; he is Shiva shown whole. The verse holds that beside mahādevāṃśa-sambhūtaṃ, 'arisen from a portion of Mahadeva', without resolving the tension. Aṃśa is a part; pūrṇākāra is the whole. Both are asserted in a single compound-chain, which is exactly the kind of doubling this literature is comfortable with and which flat readings of Bhairava as a mere attendant tend to iron out. daṇḍavat is a small joke the text does not comment on: Vishnu falls like a daṇḍa before the deity who carries one.
