There are degrees of separation between what seem to be other people’s doings and those on which we can clearly see our fingerprints. We just lose track of how we started that particular chain of events, the continuum that now brings to us this specific fruition.
Our teacher Vasubandhu said that just as a fruit does not arise immediately from a seed, a result does not arise immediately from an action; and just as a seed produces a continuum of phenomena in which a sprout produces a tree, a tree produces a flower, and a flower produces a fruit, so an action produces a continuum of mental events in which a particular development produces a specific result.
We look at the flower producing the fruit, and forget that a seed produced the sprout, and the sprout produced the tree, and the tree produced the flower that produced the fruit.
When we don’t like the fruit, when it is too sour or too bitter for our taste, we blame the tree or we blame the flower, conveniently forgetting that we planted the seed.
