Life is only one moment. Seeing is true for everybody, it is just a moment for experiencing visible object. When there is hearing there is no seeing anymore. Hearing is just a moment of experiencing sound. It does not know anything about visible object. When there are conditions for hearing we cannot help hearing. Seeing, hearing and the other realities are beyond control, they arise because of conditions and then they fall away, they are completely gone. Nobody can make them arise and nobody can make them stay on after they have arisen. Thus life goes on from moment to moment, until death. Life is only one moment of experiencing an object and then it is gone, forever.
