Streak across time

How to describe it, our existence is but a streak across time, however our life does not end, nor does it start with the particular ego you are presently acting in. Our many existences are but a streak across history. Our soul here is like a whale, swimming across the see of time, yet going to the depths of infinity, when it surfaces for air, there is your self, it goes down, that ego dies, yet you still are just as much, perhaps more, it comes up you are born again. The longitude and latitude slightly change, all is the same, all is different. This streak does not begin with this universe, nor does it end with it.
