It's impossible to pin down a single instance of what you call experience. Whatever you look at closely enough reveals that it is something else, that its nature is mirage-like. That something occurs is certain, but what that something is, where it starts and stops, is not determinable. It may be that there is only a single unchanging 'moment' of experience and all the variety and development in time that are thought to occur are part of the necessary illusion. There could not be this experience-like going on it there were not a pure experience at the back of it. This pure experience, which is completely 'alive' need not be in time and space or belong to any subject. Its nature cannot be thing-like in any way.
