శ్రీ భద్రకాలీ జగన్మఙ్గల కవచమ్

An armour from the Bhairavi Tantra called the welfare of the world, asked for by the Goddess and given by Bhairava, and its distinguishing feature is that the mantra sits inside the armour rather than beside it. Where most such texts name a goddess for each limb, this one sets seed-syllables on the body directly — krim always at the ankles, krim aim sauh at the feet with Kulasundari — so that reciting it is a placing rather than a naming. The full apparatus stands in front of it: the placing of seer and metre, the viniyoga, and a meditation. Thirty-nine units carry the whole, and the closing verse gives the usual condition in the usual words, that it is secret and to be guarded as closely as one's own person.
