REALITY AND PERCEPTION

A concept is but a concept,
Existing only in the mind.
All these words are thoughts,
Belonging to the human kind.

Nothing exists without empty space.
Without eyes, there is no sight.
The real world we call nature
Does contain no wrong or right.

Reality comes in many forms,
Much more than we can perceive.
All we know is what we know
As the words which we conceive.
