"Compassion is the awareness of a deep bond between yourself and all creatures. Next time you say, “I have nothing in common with this person,” remember that you have a great deal in common: A few years from now — two years or seventy years, it doesn't make much difference — both of you will have become rotting corpses, then piles of dust, then nothing at all. This is a sobering and humbling realization that leaves little room for pride. Is this a negative thought? No, it is a fact. Why close your eyes to it? In that sense, there is total equality between you and every other creature. ONE OF THE MOST POWERFUL SPIRITUAL PRACTICES is to meditate deeply on the mortality of physical forms, including your own. This is called: Die before you die."
Eckhart Tolle
