All our concepts are transmitted to and analysed by our consciousness. What we see, hear, smell, taste, and feel with our eyes, ears, nose, tongue and body provides information and evidence for our consciousness to judge and make decisions.
If our senses are reliable and accurate, then the information they transmit to us will not be wrong; if our senses are limited, the information they transfer to us cannot be trusted. Our five senses are not ultimately reliable, though, which can be discerned from the example of the pebble. We need to be aware that everything in this world is illusory and insubstantial.
