PARÁŚARA.--The illustrious monarch of the earth resided, Maitreya, for a considerable period at Śálagráma, his thoughts being wholly dedicated to god, and his conduct distinguished by kindness and every virtue, until he had effected, in the highest degree, the entire control over his mind. The Rájá was ever repeating the names, Yajneśa, Achyuta, Govinda, Mádhava, Ananta, Keśava, Krishńa, Vishńu, Hrishikeśa; nothing else did be utter, even in his dreams; nor upon anything but those names, and their import, did he ever meditate. He accepted fuel, flowers, and holy grass, for the worship of the deity, but performed no other religious rites, being engrossed by disinterested, abstract devotion.
