In GITA there is shloka in chapter 5 Verse 18
vidyā-vinaya-sampanne brāhmaṇe gavi hastini
śhuni chaiva śhva-pāke cha paṇḍitāḥ sama-darśhinaḥ
My thinking : I didn't deeply understand this quote
In teenage age, girl is attracted to a handsome boy, boys are attracted to beautiful girls. But we are not attracted to ugly face girls or ugly face boys.
My question is that how can we look equally to ugly face girls/boys and beautiful face boys/girls?
Is there any technique?
