Mbh 3.36.4

That foremost of speakers then, the son of Parasara, taking Yudhishthira to a corner, began to address him in words of deep import, saying, ‘O best of the Bharatas, the time is come for thy prosperity, when, indeed Dhananjaya--that son of Pritha--will slay all thy foes in battle. Uttered by me and like unto success personified, accept from me this knowledge called Pratismriti that I impart to thee, knowing thou art capable of receiving it. Receiving it (from thee), Arjuna will be able to accomplish his desire. And let Arjuna, O son of Pandu, go unto Mahendra and Rudra, and Varuna, and Kuvera, and Yama, for receiving weapon from them. He is competent to behold the gods for his asceticism and prowess. He is even a Rishi of great energy, the friend of Narayana; ancient, eternal a god himself, invincible, ever successful, and knowing no deterioration. Of mighty arms, he will achieve mighty deeds, having obtained weapons from Indra, and Rudra, and the Lokapalas, O son of Kunti, think also of going from this to some other forest that may, O king, be fit for thy abode. To reside in one place for any length of time is scarcely pleasant. In thy case, it might also be productive of anxiety to the ascetics. And as thou maintainest numerous Brahmanas versed in the Vedas and the several branches thereof, continued residence here might exhaust the deer of this forest, and be destructive of the creepers and plants.’”
