We worship Sraosha [Obedience] the blessed, whom four racers draw in
harness, white and shining, beautiful and (27) powerful, quick to learn
and fleet, obeying before speech, heeding orders from the mind, with
their hoofs of horn gold-covered, (28) fleeter than [our] horses,
swifter than the winds, more rapid than the rain [drops as they fall];
yea, fleeter than the clouds, or well-winged birds, or the well-shot
arrow as it flies, (29) which overtake these swift ones all, as they fly
after them pursuing, but which are never overtaken when they flee, which
plunge away from both the weapons [hurled on this side and on that] and
draw Sraosha with them, the good Sraosha and the blessed; which from
both the weapons [those on this side and on that] bear the good
Obedience the blessed, plunging forward in their zeal, when he takes his
course from India on the East and when he lights down in the West.
