This following is a rare amulet prayer of Lord Krishna from Sri Garga Samhita, Goloka
Khanda, Chapter 13. This prayer was chanted by Gopis when Lord Krishna gave Moksha to
Putana. The short Phalashruti mentions that this Kavacham bestows all protection to the
chanter and was given by Lord Hari himself to Lord Brahma who in turn gave it to Lord
Shiva, Lord Shiva to Sage Durvasa and Sage Durvasa to Yashoda in the sactum of Nandi.
