भयाद्रणादुपरतं मंस्यन्ते त्वां महारथाः। येषां च त्वं बहुमतो भूत्वा यास्यसि लाघवम्॥
bhayad ranad uparatam mamsyante tvam maharathah yesham cha tvam bahumato bhutva yasyasi laghavam
Translation
The great warriors will think you withdrew from battle out of fear, and those who held you in high esteem will look upon you with contempt.
Commentary
Krishna points out the practical social consequences. Warriors who respected Arjuna will lose respect for him, thinking he fled from cowardice. This is a powerful motivator for a warrior's psychology.
