yo'yaṃ dhuraṃ dhuryavaro vāmaṃ vahati śobhanaḥ |
taṃ manye meghapuṣpasya javena sadṛśaṃ hayam || 19 ||

"Uttara said, 'Thou hast conferred a great favour on me today, for I now find that my suspicion was not altogether unfounded. Indeed, such a person as thou, O best of men, cannot be of the neuter sex. I have now an ally in battle. I can now fight with the celestials themselves. My fears have been dispelled. What shall I do? Command me now. Trained in driving cars by a learned preceptor I will, O bull among men, hold the reins of thy horses that are capable of breaking the ranks of hostile cars. Know me, O bull among men, to be as competent a charioteer as Daruka of Vasudeva, or Matali of Sakra. The horse that is yoked unto the right-hand pole (of thy car) and whose hoofs as they light on the ground are scarcely visible when running, is like unto Sugriva of Krishna. This other handsome horse, the foremost of his race, that is yoked unto the left pole, is, I regard, equal in speed to Meghapushpa. This (third) beautiful horse, clad in golden mail, yoked unto the rear-pole on the left, is, I regard, Sivya equal in speed to but superior in strength. And this (fourth) horse, yoked to the rear-pole on the right, is regarded as superior to Valahaka in speed and strength. This car is worthy of bearing on the field of battle a bowman like thee, and thou also art worthy of fighting on this car. This is what I think!'
