I may try become a better person today than a person that exists in yesterday. But the definition of being better itself is a cloudy definition.
I may become someone better on a scale of many limitations. I am learning so I am better in knowledge. But knowledge is always limited. So within this small border, exist a better me from time to time, but time also a limited dimension.
How if I stand within a world without boundaries? How if I am the limitless universe? Shall I have a better today? Which day I shall compare to get a better form of limitless universe.
When I find myself as a form that part of world that full of limitations. Then I shall find a better today. When I stand as a limitless universe, than all the days cease to exist as compared consciousness.
