A firm and fixed belief in that which is based on inadequate grounding
A delusion is a belief held with strong conviction despite superior evidence to the contrary.

- What the Buddhists teach is to free yourself from the three great evils in life: greed — which means all kinds of craving — hatred, and delusion. But delusion is really the cause of the other two. We crave that which we delude ourselves into thinking will bring happiness; we hate those whom we delude ourselves into thinking stand to stop us from getting it.

- Adam: Nature mandates that mankind will eventually succumb to its poison. However, humans created their own poison, called medicine. It's delusional to believe you can poison Nature to avoid your fate.

- Delusion will vanish as the light becomes more and more effulgent, load after load of ignorance will vanish, and then will come a time when all else has disappeared and the sun alone shines
- Swami Vivekananda, Pearls of Wisdom.
- We all have our little solipsistic delusions, ghastly intuitions of utter singularity: that we are the only one in the house who ever fills the ice-cube tray, who unloads the clean dishwasher, who occasionally pees in the shower, whose eyelid twitches on first dates; that only we take casualness terribly seriously; that only we fashion supplication into courtesy; that only we hear the whiny pathos in a dog's yawn, the timeless sigh in the opening of the hermetically-sealed jar, the splattered laugh in the frying egg, the minor-D lament in the vacuum's scream; that only we feel the panic at sunset the rookie kindergartner feels at his mother's retreat. That only we love the only-we. That only we need the only-we. Solipsism binds us together, J.D. knows. That we feel lonely in a crowd; stop not to dwell on what's brought the crowd into being. That we are, always, faces in a crowd.
