having beautiful wings —

pure nectar (which is not mixed with supremacy and only presenting simplicity) —

while going as a messenger sent by me —

the message saying -ẏou, being kĕṣava, are to eliminate my klĕṣa (sorrow)- —

 ŏh my pure heart! —

being my messenger —

going as my messenger —

 to say that he is the messenger of pāṇdavas —

the sages who are of pure conduct, —

 went as messenger —

no purity at all (without lust, anger etc) —

 went as messenger —

 one who mercifully went as divine messenger —

if one offers flowers and worships —

is the mountain which stimulates —

submitting fresh flowers —

submit good flowers, —

 offering the best flowers and other things for worship —

 submitting the best flowers —

having pure mind (which does not hanker for ulterior goals) —
