Enlightenment is not ecstasy. It is not knowing everything there is to know. It is not becoming a world leader. It is not becoming a savior of 1000s of people. Neither is it service to anyone or any group. Externally there is literally no difference between an enlightened person and non-enlightened. The one who knows himself is enlightened, the one who does not is not. Its like a marigold that knows its a marigold is enlightened. A marigold which thinks its a rose is not.
Enlightenment is the satisfaction of the ultimate deepest knowing. Experiences come and go, but the understanding stays. Sometimes the understanding leaves, but then there is another understanding that stays behind it. This happens all the way until emptiness.
