avyaktādīni bhūtāni vyakta-madhyāni bhārata |
avyakta-nidhanāny-eva tatra kā paridevanā || 2.28 ||

The being of all beings is indistinct, equally so their end too is indistinct, unknown. Their middle state alone is distinct. What is the use of any affliction then?

Note: How can we deal with life with any mastery, as neither its beginning or end is known to us. The middle manifestation is alone available for us. Nothing hence should lead to grief or remorse.
