It's generally assumed that the universe is limited and that individuals are limited. It is considered that the universe has a beginning and an end in time and space. It's also thought that we are individual beings with beginnings and endings. How can I put this? It's just not true, and there really has never been any valid evidence to say it is true. Let's explore it and see what the evidence shows.
No-one has ever found the beginning or end of time or space. It is generally accepted that the universe appeared from a singularity, bursting forth into expression, outwards from this centre. It is this bursting forth that is space and time itself. Before time and space the singularity was in a spaceless place timelessly. Only when the explosion of the universe happened could it be later said that it began there. But we can't really say when it began, because there was no time before, then there suddenly seemed to be time. Similarly with space, in the singularity there was no reference of separation and distance, so there was no space before space suddenly seemed to appear.
Really, if we consider the beginning of the universe we find that space begins in the infinite and time begins in the timeless, which means that the universe has no beginning or end. Similarly, if we look towards the end of the universe, space can only come to an end in the infinite, and time can only come to an end in the timeless. Where are the limits we have assumed were there? They cannot be found. If there were limits to the universe then that would mean there was something other or outside the universe limiting it. But when we consider that the universe includes everything, then there can't be anything else.
If we look at our individual limits, generally humans assume they are limited by the body, and anything that is not the human body is not them. But there are no fixed limits to the human body. The outer layer or skin isn't really separate from the environment. The skin is constantly being replaced by new skin as the old skin flakes off into the environment. Air flows into and out of the body. Food and liquids come into the body and go out. Really the body is a constantly changing appearance of a life form made of and within the planet. The body is never really separate from the planet, so the body is never really limited.
So our ideas of limitation are flawed. There is no limitation. That means there is no 'me'. What we think we are is not really who we are. We cannot be defined. We are nothing other than what the universe is. There is no real outside or inside of 'me'. Although there are thoughts that we are the thinker and the body, and everything else is outside us, that's not true. Thoughts are perceived but there is no limited individual that perceives them. Thoughts of being limited or not are perceived. The sense of identity is perceived, but there is no true identity, because identity means separation from what it is not, and that doesn't happen because there are no true limits that divide.
So where does this leave us and the universe? We are the universe. There are no others. There is only This. It means we can drop the old beliefs of limitation and live freely. Although there may appear to be limitations, we know that limitations are only make believe. We have no beginning or end. We have no restriction. We are freedom itself. The full recognition of this we call Liberation, Moksha or Enlightenment, where the sense of separate identity is cast aside and we are as we are.
