வஸிஷ்டப்ரோக்தம் த்ரைலோக்யவிஜயகவசஸ்தோத்ரம்

Vasishtha gives this armour to Sagara in the thirty-third chapter of the middle part of the Brahmanda Purana, and it is built around the ten-syllabled Gopala mantra, which the third verse spells out by description rather than setting down plainly. Two sets of credentials are given, one for the mantra and one for the armour — Sadashiva as seer of the first and Prajapati of the second, with Krishna named as the deity of both. What follows places a different form of the name over each part of the body in turn: Om at the head, Krishna at the eyes, Hari at the brows, Govinda at the nose, Gopala at the cheek, Gopisha at the rows of teeth, through some thirty verses. It ends on the warning that belongs to the form and is part of it — give away your kingdom, give your head, give your life, but do not give this away, not even in extremity.
