śrī kamalā kavacam

An armour of Kamala from the Vishvasara Tantra, named there as the armour of the four-syllabled mantra of Vishnu's consort. It opens with the claim that gives it its standing: now, great mistress, I shall tell the armour that gives every desire, by the mere knowing of which one becomes Sadashiva himself. The second verse then says something unusual for the form — that for such a person there is no need of formal worship at all, only the repetition of the mantra; he becomes as Parvati's son, one who has crossed to the far side of every scripture, and the goddess is especially to be served by those who want learning. That last clause matters: this Kamala is asked for knowledge as much as for wealth, which is not where Lakshmi's reputation usually sits.
