Contemplating the truth about existence invites us to let go of our attachment to hope that we will gain something and fear that we will lose it. It gives us the perspective to see that life is constantly happening to us, and that's okay. What causes suffering is our desire for things to be a certain way.
Most of us wake up in the morning with a faulty assumption that we are going to get happiness by dividing our day into what we want to happen and what we don't want to happen, into those who are for us and those who are against us. True victory is not being caught by the illusion of permanence. This freedom allows us to extend ourselves outrageously, with wisdom and compassion in all worlds.
There is a story of a woman running away from tigers. She runs and runs and the tigers are getting closer and closer. When she comes to the edge of a cliff, she sees some vines there, so she climbs down and holds on to the vines. Looking down, she sees that there are tigers below her as well. She then notices that a mouse is gnawing away at the vine to which she is clinging. She also sees a beautiful little bunch of strawberries close to her, growing out of a clump of grass. She looks up and she looks down. She looks at the mouse. Then she just takes a strawberry, puts it in her mouth, and enjoys it thoroughly. Tigers above, tigers below.
This is actually the predicament that we are always in, in terms of our birth and death. Each moment is just what it is. It might be the only moment of our life; it might be the only strawberry we’ll ever eat. We could get depressed about it, or we could finally appreciate it and delight in the preciousness of every single moment of our life.
