PARÁŚARA.--There was Janaka, named Dharmadhwaja, who had two sons, Amitadhwaja and Kritadhwaja; and the latter was a king ever intent upon existent supreme spirit: his son was the celebrated Keśidhwaja. The son of Amitadhwaja was Janaka, called Kháńd́ikya. Kháńd́ikya was diligent in the way of works, and was renowned on earth for religious rites. Keśidhwaja, on the other hand, was endowed with spiritual knowledge. These two were engaged in hostilities, and Kháńd́ikya was driven from his principality by Keśidhwaja. Expelled from his dominions, he wandered with a few followers, his priest and his counsellors, amidst woods and mountains, where, destitute of true wisdom, he performed many sacrifices, expecting thereby to obtain divine truth, and to escape from death by ignorance.
