But "shuklAmbaradharam" (white-clad) is also used in Mahabharata to describe droNa's entry to "Rangabhumi" at the "Graduation" ceremony of the princes!
Then the preceptor (drONa) entered the arena with his son. He was dressed in white garments and wore a white sacred thread. His hair and beard were white. He wore a white garland and was anointed with white paste"
Shouldn't the second verse come first, then followed by the first verse that describes the teacher's garments?
