The unenlightened state is really just a state of denial. If you could just be completely honest with yourself, you would Know the Truth immediately. You only choose to be deceived to perpetuate your bogus desires and convictions.
Just as the wisp of cloud shrouds the magnificence of the sun, so too does that which you cling to overshadow the grandeur of your true nature.
“We are never deceived; we deceive ourselves.” – Johann Wolfgang von Goethe
