We refer to enlightenment as liberation from the wheel of Samsara—the eternal cycle of birth, suffering, death, and rebirth. This idea of liberation implies that there is a sequence of events, a subtle pathway through the maze that leads to an exit, to freedom from the wheel. Thus the idea that some kind of action—positive actions of goodness, of generosity—will lead one to liberation.
Yet there is no perceivable causal relationship between action of any kind and enlightenment. The process of enlightenment lies somewhere at the intersection of what we would call intent and luck. Enlightenment is something you catch by running into it, propelled by a complex weave of chance and the dynamic of destiny, the intention of existence.
