శివప్రోక్తం త్రిపురాకవచమ్

An armour of Tripura spoken by Shiva to Vetala and Bhairava, from the seventy-fifth chapter of the Kalika Purana, and it enters at verse fifty where that chapter places it. Hear the armour of Tripura, Vetala, Bhairava; knowing which rightly, one who knows the mantra obtains the fruit in worship. The verse that follows ties it to the ritual it belongs inside — the services were described before, and the same understanding declared there holds here in the daily worship — which is a useful reminder that a kavacha of this kind is a section of a liturgy rather than a standalone hymn. Forty-four verses set her syllables over the body and close the quarters in the manner of the form.
