Who says what reality is? Whose ego is so confident to say they know what reality truly is? How can one say what is true and not true? We're all fragment of our imagination in this human experience. Who are we to have all the answers?

Who are we? What makes your concept of reality any better than another? Who are you to preach? The educated mind challenges old ways of thinking and continually grows.... Would it be so hard to accept that our reality or what we feel is "truth" is wrong? At the end of the day, what does it even matter. The only moment that matters is "now".
Whose "delusion" will you make into your "illusion"?
