Bhagavad Gita 2.11
śrī-bhagavān uvāca
aśocyān anvaśocas tvaṁ
prajñā-vādāṁś ca bhāṣase
gatāsūn agatāsūṁś ca
nānuśocanti paṇḍitāḥ
The Supreme Personality of Godhead said: While speaking learned words, you are mourning for what is not worthy of grief. Those who are wise lament neither for the living nor for the dead.
