Enlightenment is nothing other than the state beyond all obstacles, in the same way that from the peak of a very high mountain one always sees the sun. Enlightenment is not a paradise or some special place of happiness, but it is in fact the condition beyond all dualistic concepts, including those of happiness and suffering.
When all our obstacles have been overcome, and we find ourselves in a state of total presence, the wisdom of enlightenment manifests spontaneously without limits, just like the infinite rays of the sun. The clouds have dissolved, and the sun is finally free to shine once again.
