Vaisampayana continued, "Having addressed him thus, that illustrious and exalted ascetic Vyasa, of great wisdom, acquainted with the mysteries of the world, then imparted unto the willing Yudhishthira the just, who had meanwhile purified himself, that foremost of sciences. And bidding farewell unto the son of Kunti, Vyasa disappeared then and there. The virtuous and intelligent Yudhishthira, however, having obtained that knowledge carefully retained it in his mind and always recited it on proper occasions. Glad of the advice given him by Vyasa, the son of Kunti then, leaving the wood _Dwaitavana_ went to the forest of _Kamyaka_ on the banks of the Saraswati. And, O king, numerous Brahmanas of ascetic merit and versed in the science of orthoepy and orthography, followed him like the Rishis following the chief of the celestials. Arrived at _Kamyaka_, those illustrious bulls amongst the Bharata took up their residence there along with their friends and attendants. And possessed of energy, those heroes, O king, lived there for some time, devoted to the exercise of the bow and hearing all the while the chanting of the Vedas. And they went about those woods every day in search of deer, armed with pure arrows. And they duly performed all the rites in honour of the _Pitris_, the celestials and the Brahmanas." SECTION XXXVII Vaisampayana said, "After some time, Yudhishthira the just, remembering the command of the _Muni_ (Vyasa) and calling unto himself that bull among men--Arjuna--possessed of great wisdom, addressed him in private. Taking hold of Arjuna's hands, with a smiling face and in gentle accents, that chastiser of foes--the virtuous Yudhishthira--apparently after reflecting for a moment, spake these words in private unto Dhananjaya, 'O Bharata, the whole science of arms dwelleth in Bhishma, and Drona, and Kripa, and Karna, and Drona's son. They fully know all sorts of _Brahma_ and celestial and human and _Vayavya_ weapons, together with the modes of using and warding them off. All of them are conciliated and honoured and gratified by Dhritarashtra's son who behaveth unto them as one should behave unto his preceptor. Towards all his warriors Dhritarashtra's son behaveth with great affection; and all the chiefs honoured and gratified by him, seek his good in return. Thus honoured by him, they will not fail to put forth their might. The whole earth, besides, is now under Duryodhana's sway, with all the villages and towns, O son of Pritha, and all the seas and woods and mines! Thou alone art our sole refuge. On thee resteth a great burden. I shall, therefore, O chastiser of all foes, tell thee what thou art to do now. I have obtained a science from Krishna Dwaipayana. Used by thee, that science will expose the whole universe to thee. O child, attentively receive thou that science from me, and in due time (by its aid) attain thou the grace of the celestials. And, O bull of the Bharata race, devote thyself to fierce asceticism.
