Our senses have to be seen as some kind of instruments nature has provided to us to experience the phenomena around us. These senses more or less have to be considered to be phenomena themselves. This consequently means that we are confronted with limits of what we can know and understand about the world around us and the true nature behind it. You can say the world around us, since it is perceived by us, in some way is real but due to the limits of our perception this ‘reality’ in its essence is actually not the way we assume it is.
A key question in this mystery is how do we actually know the world and to which degree does our perception represent the true nature of the world?
To a certain level it is possible to assert that every single individual perceives a different – individual – world. This is because our human nature not only knows judgments that are universally true (for example mathematical measurements that are always showing the same result irrespective of the person carrying it out) but every human being also makes judgments that are based on personal experience (for example feeling warm or cold, or the like or dislike of a book, etc.). Besides these re-measurable facts, for a huge part we perceive the world according a mixture of our intellectual composition and our surrounding (culture, social background, etc.). And this mixture is for each single individual different. Our intellect and self-awareness in form of our ego has to be considered as some individual illusion. For this reason our perceptions are also categorized by our own individual mind and each individual more or less projects his individual world. The limitations of the individual mind do not enable us to understand the common non-changing essence beyond all those different individual perceptions.
We define the phenomena around us based on space and time. Just like our bodily senses this intuition of space and time is given to us by nature. From beginning we have understood those concepts by intuition, not by experience. How would it also be possible to have experienced them? Space for example we intuitively consider to be infinite. This is not possible to prove or experience. Same counts for our perception of time. By intuition we consider it infinite. We can imagine that over a certain stretch of time nothing at all would happen, but it is impossible for us to imagine that there would not be time at all?
In our human thinking this concept of wholeness we might reach through pure reasoning will have its most important limitation in the fact that the way we understand it in our individual mind it is contradictory. The concept of wholeness as we know it implies a boundary. According to the reasoning determined by the structure of our mind only within a boundary something can be whole or complete. But then what is beyond this boundary? And having a boundary how then could we define this wholeness to be infinite? So it is exactly this contradiction that touches the limits of our reasoning.
