Enlightenment is knowing that I do not exist in the Universe that is perceived.
There is this Universe. an infinite variety of shapes, forms, names, colors, movement, ideas, comings, goings, interactions, collections, relations, interpretations, values, valuations, directions, orientations, information, communications, creations and what not.
There are certain very interesting and entertaining entities called people. they seem to have a mind of their own. they also seem to have their own individual existence. There are lots of people. there seems to have been lots of people, and more people seem to be on the way.
The Universe in general though appears unimaginably large, it seems to focus around the entities called people. the ideas, actions, and communications of people seem to define the world.
Of all the people in the world, there seem to be a particular person , whose mind I seem to have access to. I can see his thoughts, I can see his emotions, I can see his view of the world. Of course I am certain that I am not this person, just that I seem to have some access to his mind. In spite of knowing and apparently interacting with this world to a good extent, I am not part of it.
Sometime ago I realized that I do not exist in this Universe. But I do exist. So this Universe of variations, is apparent, similar to the Universe in a dream. Though I seem to experience the dream, I am not inside the dream. so my experience is also only apparent.
The world of experiences, and the experience it seems to offer , all of it being disconnected and apparent, it is indeed strange that I get concerned about things. But ... concerns and anxieties, rejoicing and fun, all are part of the World where I do not exist.
Realizing that I alone exist, which can neither act, not experience and disconnected by this world which is nothing but a drama of light and sound, the I stays in its own state of bliss.
