Be kind wherever possible… It is always possible.
Do I remember at every moment that I am dying, and everyone and everything is, and so treat all beings at all times with compassion?
Slightly morbid but makes so much sense! If you got hit by a bus tomorrow would you have any regrets for the ways you treated people today?
Update: I originally thought this was a quote from Buddha but Chico nicely pointed out that I was very much wrong! Sorry guys! :)
