Bhagavad Gita 1.27 · Sanjaya
On both sides of the line
श्वशुरान्सुहृदश्चैव सेनयोरुभयोरपि।
तान्समीक्ष्य स कौन्तेयः सर्वान्बन्धूनवस्थितान्॥
śvaśurānsuhṛdaścaiva senayorubhayorapitānsamīkṣya sa kaunteyaḥ sarvānbandhūnavasthitān
He saw fathers-in-law and dear friends in both armies, and looking at all these kinsmen standing there, Arjuna was overcome.
What it means
The list goes on. Fathers-in-law. Well-wishers. And Sanjaya adds a painful detail, in both armies. Arjuna's own side is full of family too. Whoever wins, his family loses. Kaunteya, son of Kunti, takes it all in, and something gives way.
The story
Arjuna is called Kaunteya here, his mother's son. Kunti is the mother of the Pandavas and also, secretly, of Karna on the other side. The family ties run through both armies like roots under a field. No arrow could miss them all.
In your life
Picture a divorce where the friends and grandparents are split down the middle. Children shuttle between two homes. When you're in a conflict, remember the people caught between you. Protect them where you can.
In some battles, everyone loses someone.
