Maitri karuna mudito pekshanam
sukha dukha punya apunya visayanam
bhavanatas citta prasadanam

For me, this sutra can inform every interaction we have with another person, as well as the way we treat ourselves.  In the moments where I have been able to live by this sutra, I’ve found a noticeable reduction in stress or irritation, and feel much more uplifted at the end of each day.  Greeting suffering with empathy and non-virtue with nonattachment have made the largest difference in my life; by removing ourselves, and any comparison to ourselves, from a relationship with someone who is struggling, we are able to serve each other better.  And with that comes incredible ease of mind. 

I also like the many translations of the active verb (visayanam) that I’ve read: cultivate, meet, have an attitude of, regard.  The English translations convey varying levels of passivity; for me, the active verbs (greet, cultivate) are the most empowering.

I love this sutra.  I think about it all the time, especially in moments of frustration.  I want to tell everyone about it.
