We can see it as a kind of some photo album in which, photos are arranged in chronological order. When we see the photos, we try to feel the moments in the same chronological order. Another example could be watching a movie. Sometimes we get engrossed to the movie so that we feel as if we are part of the happenings in the movie. Similarly why not even the life that we experience is also some kind of album and we simply journey through it?
In essence, everything is pre-determined; the inputs for our brain for our every thinking/feeling is already made; and we simply consume them.
