I guess you mean the background? If so then there is no real difference between foreground and background other than a change in colour and tone. A contrast between shapes. Foreground and Background are again just concepts/labels.And the back. Were you able to describe the back? And how comes?
Actually I have never believed that time exists. It's just a concept that is used to describe changes in events and movement. Because we know that there is change, we assume there must be time, but there is no actual experience of a thing that is time.How is it known that there is movement?
Movement includes the idea of time, of something that starts, covers some time and then ends, a before and after, right?
Have a look:
However, I do believe there is movement. Reality to me seems to be experienced as a constantly changing dance of energy. Everything is moving on some level, even down to the vibration of atoms. If I stand in front of a moving car, I'm going to get squashed. So movement is definitely happening, but I don't see that it has a beginning and end, there is just 'flow' from one seeming event to the next.
Actually there is no 'one event to the next'. There are no 'events' as there is no way of finding a definite start or finish. This feeling of movement/change is different for each person (experiencer). For some it is fast for some it is slow but it's all just change...
Also, there is no 'present moment'. That too would imply that there are other moments than the present one. Not so. There are no moments. Just a constant movement of energy.
