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.'
