śrī mātaṅgī kavacam (sumukhī kavacam)

An armour of Matangi, called in its own heading the armour of the fair-faced one, and it opens with Parvati asking Shiva for it on a condition — tell me the armour of Matangi, if you have any love for me. The armour proper is made of her mantra broken across the body, so that Ucchishta-chandali Matangi, subduer of all, svaha, guards one part and the destroyer of every enemy the next. Directions for the practice and for wearing the written armour follow it. The closing verse gives the claim these texts make for themselves in its strongest form: one who repeats Matangi's mantra without knowing this armour gains nothing by it, even after a hundred thousand preliminary repetitions.
