The Sri Guna Ratna Kosha is an exquisite poem by Swami Parasara Bhattar in praise of the infinite, infinitely auspicious virtues of the Supreme Goddess Mahalakshmi. As he was the chief priest for the grand temple of Lord Ranganatha in Srirangam, he pays special attention to Ranganayaki Thayar. Sri Parasara Bhattar also devotes special attention to Sita Devi and Her compassion which exceeds even Lord Rama's.
