Space has no limits. If we look up on a clear night our vision is only limited by the distant light being able to reach the eye. There is no end to the universe.
If we look down a street as far as a building that blocks our view it is only an appearance of solidity that prevents light traveling through it. The building isn't truly a limitation. It isn't truly completely solid. Although light can't pass through the bricks of the building, light is only a range of the electromagnetic spectrum. Other ranges of the electromagnetic spectrum can pass through it. Limitations are illusory.
There is no end to the space outside us or inside us. Truly there is no outside or inside. There is no real division to make it so. Our understanding of inside and outside is conceptual and based on the appearance of limitation of form. But there is no real limitation. The human body, for example, is a flowing form. It's porous, and although it seems to have an outer shell there is no real separation between the 'inside' and 'outside'. There is only a conceptual inside and outside.
So the space ahead of us, inside us, and behind us is simply unlimited space, Infinite Space. To go even further, really there is no space. The appearance of distance that gives the illusion of space is created by the seeming solidity of forms. The space is the place these forms take and the distance between them. Or so it seems.
The Infinite Space is No Space. It is all right Here. No-one has experienced any place other than here. We may perceive places 'over there' but once we get there we are still Here. Distance and space are only an appearance in the No Space right Here.
Where is Here? It cannot be described as it is the only place, but it is no place. It is no distance from anything. There is no distance. Yet this Infinite Spaceless Space allows the appearance of space and limitation.
