The same to friend and foe

samaḥ śatrau ca mitre ca tathā mānāpamānayoḥśītoṣṇasukhaduḥkheṣu samaḥ saṅgavivarjitaḥ

The same to foe and friend, in honour and dishonour, in cold and heat, in pleasure and pain, free of clinging...

What it means

Krishna continues. The devotee is the same toward enemy and friend. The same in honour and insult. The same in cold and heat, pleasure and pain. Free of clinging. Not that they can't tell the difference, but that their inner balance and goodwill don't change.

The story

Arjuna is about to face cousins as enemies. Krishna asks him to keep the same inner fairness toward them that he has for friends. That's what makes a warrior noble.

In your life

Think of a referee who treats both teams with exactly the same fairness, whatever the crowd shouts. Treat someone you dislike today with the same courtesy you'd show a friend.
