śrī śivapadamaṇimālā stotram

A jewelled garland on the word Shiva itself, given by its colophon to Shankaracharya, and every verse of the forty-one begins with the same three words — these two syllables, shi and va — and then finds another thing they are. They are the two wings of the swan that carries one to the highest state; the two banks of the sea of becoming; the two petals on which the sprout of knowledge of one's own object opens; the secret hidden inside the Veda, moving in the heart; the two millstones for grinding the seed-mass of the tree of existence. The next verse gives them again as the pillar-and-pot of victory over birth, as skilled at destroying inner darkness, and as the chamberlains who bring the crowd to the head of the great procession.
