If you look without a centre at the whole of existence, there is no time. And that is the most mysterious part of it. Time is one of the most complex things to understand – not intellectually, that’s fairly simple, but the nature of time, the significance of time, the depth of time. To understand it, to see the meaning of it, one has not only to understand chronological time by the watch, but also to understand, to observe the psychological thing that creates time as yesterday, today and tomorrow.
