Most of us tend to view everything through the perception of what we can see. That is how we define what is real or what is our reality. Yet vision is just one of the many ways we can choose to define what determines whether or not something exists or how it exists and is therefore deemed to be the reality.  Simply because we cannot see something does not render it an impossibility or deny its existence. We know that we have other senses yet we have apportioned more weight to the realm of seeing is believing. If we were blind then sound could become our primary source of reality and we would similarly appoint that sense as our definition of what is real. Let us assume that we have neither of those faculties: what becomes our medium for defining reality? Touch? Taste? Smell? What if none of these five sense are available to us? Does that mean that there exists nothing? We deny ourselves access to the greater part of the Universe simply because we have chosen to define our understanding of reality as that which can be interpreted by our five senses. If we look beyond those limitations and open ourselves up to all possibility then we will sense a much more accurate picture of what is reality.
