Mbh 3.167.1c

Do thou, O Bharata, repairing unto my abode learn all the weapons of Vayu, of Agni, of the Vasus, of Varuna, of the Marutas, of the Siddhas, of Brahma, of the Gandharvas of the Uragas, of the Rakshasas, of Vishnu and of the Nairitas; and also all the weapons that are with me, O perpetuator of the Kuru race.’ Having said this unto me Sakra vanished at the very spot. Then, O king, I saw the wonderful and sacred celestial car yoked with steeds arrive conducted by Matali. And when the Lokapalas went away Matali said unto me. ‘O thou of mighty splendour, the lord of the celestials is desirous of seeing thee. And O mighty-armed one, do thou acquire competence and then perform thy task. Come and behold the regions, attainable by merit and come unto heaven even in this frame. O Bharata, the thousand-eyed lord of the celestials wisheth to see thee.’ Thus addressed by Matali, I, taking leave of the mountain Himalaya and having gone round it ascended that excellent car. And then the exceedingly generous Matali, versed in equine lore, drove the steeds, gifted with the speed of thought or the wind. And when the chariot began to move that charioteer looking at my face as I was seated steadily, wondered and said these words, ‘Today this appeareth unto me strange and unprecedented that being seated in this celestial car, thou hast not been jerked ever so little. O foremost of Bharata race, I have ever remarked that at the first pull by the steeds even the lord of the celestials himself getteth jerked. But all the while that the car had moved, thou hast been sitting unshaken. This appeareth unto me as transcending even the power of Sakra.’
