everything is layered...there are multiple levels of reality for each moment, there's the event which is in-of-itself occurring, there is your experience of the event occurring, there is your perception of the experience which is happening, there is also our perception of what we perceive (how we feel about what we are feeling if you will)...and those are but four of the layers occurring within an individual, once a 'other' is incorporated the layers multiply...some seek to eliminate the extraneous layers, zen practitioners for example, others live in the multitude
