Sri Bhagavan Uvacha –
You are speaking like a learned man, but you are lamenting on something which is not worthy of lamentation. The learned men will neither lament for the living nor the dead.
Sri Krishna is saying you are talking like a learned man, but you are not acting like one(hence the smile in the previous verse?). Because learned men will not lament for the living nor the dead.
Crying because one is still alive – lol 🙂
I guess Sri Krishna is saying that the wise men will see both the alive and the dead equally.
