Bhagavad Gita 2.27
जातस्य हि ध्रुवो मृत्युर्ध्रुवं जन्म मृतस्य च।
तस्मादपरिहार्येऽर्थे न त्वं शोचितुमर्हसि।।2.27।।
Jatasya hi dhruvo mrityurdhruvam janma mritasya cha
Tasmadapariharyerthe na tvam shochitumarhasi
Simple meaning, written by AIDeath is certain for the born, and birth is certain for the dead. Therefore, you should not grieve over what cannot be avoided.
