Gita chapter 2 verse 11
śhrī bhagavān uvācha aśhochyān-anvaśhochas-tvaṁ prajñā-vādānśh cha bhāṣhase gatāsūn-agatāsūnśh-cha nānuśhochanti paṇḍitāḥ
Meaning :The wise lament neither for the living nor for the dead.
My question :why Lord krishna say that wise lament neither for the living nor for the dead ?.What is the purpose of this statement ?
