Bhima found that he had sunk down to the city of serpents, which is in the underworld. Vasuki, king of the Nagas, having heard of his prowess, hastened towards the young warrior, whom he desired greatly to behold.
Bhima was welcomed by Aryaka, the great grandsire of Pritha, who was a dweller in the underworld. He was loved by Vasuki, who, for Aryaka's sake, offered great gifts to fearless Bhima. But Aryaka chose rather that the lad should be given a draught of strength which contained the virtues of a thousand Nagas. By the king of serpents was this great boon granted, and Bhima was permitted to drain the bowl eight times. He immediately fell into a deep slumber, which continued for the space of eight days. Then he awoke, and the Nagas feasted him ere he returned again unto his mother and his brethren, who were mourning for him the while. Thus it fell that Bhima triumphed over Duryodhana, for ever afterwards he possessed the strength of a mighty giant. He related unto his brothers all that had befallen him, but they counselled him not to reveal his secret unto the Kauravas, his cousins.
About this time the prudent Bhishma deemed that the young men should be trained to bear arms; so he searched far and wide for a preceptor who was at once a warrior and a scholar, a pious and lofty-minded man, and a lover of truth. Such was Drona, the brave and god-adoring son of Bharadwaja. He was well pleased to have care of the princes, and to give them instruction worthy of their rank and martial origin.
Drona had no mother: his miraculous birth was accomplished by a beautiful nymph, and his sire was Bharadwaja, a most pious Brahman. Of similar origin was Drupada[225], son of a rajah named Prishata[226]. Drona and Drupada were reared together like brothers by the wise Bharadwaja, and it was the hope of both sires that their sons would repeat their own lifelong friendship. But when, after happy youth, they grew into manhood, fate parted them. The rajah retired from the throne, and Drupada ruled the kingdom of Panchala[227]. Bharadwaja died soon afterwards, and Drona married a wife named Kripa, who became the mother of his son Ashwatthama[228]. The child was so named because at birth he uttered a cry like to the neighing of a horse. Drona devoted himself to rearing his son, while he accumulated the wisdom of the sages and performed sacred rites with pious mind like to his holy sire.
