Bhagavad Gita 2.11

भगवान श्रीउवाच |
अशोच्यानन्वशोचस्त्वं प्रज्ञावदंश्च भाषसे |
गतासूनगतासूंश्च नानुशोचन्ति पण्डिता:

Translation

The Supreme Lord said: While you speak words of wisdom, you are mourning for that which is not worthy of grief. The wise lament neither for the living nor for the dead.
