Candrakrti, who lived in India in the 7th century CE, is a major Mahayana Buddhist scholar whose works are studied in modern western universities and traditional Tibetan Buddhist monasteries. This is a translation of the first four chapters of Candrakrti's commentary on Aryadeva's 400 Stanzas.

Wiggling a pencil so that it looks like it is made of rubber, "stealing" your niece's nose, and listening for the sounds of the ocean in a conch shell– these are examples of folk illusions, youthful play forms that trade on perceptual oddities. In this groundbreaking study, K. Brandon Barker and Claiborne Rice argue that these easily overlooked instances of children's folklore offer an important avenue for studying perception and cognition in the contexts of social and embodied development. Folk illusions are traditionalized verbal and/or physical actions that are performed with the intention of creating a phantasm for one or more participants. Using a cross-disciplinary approach that combines the ethnographic methods of folklore with the empirical data of neuroscience, cognitive science, and psychology, Barker and Rice catalogue over eighty discrete folk illusions while exploring the complexities of embodied perception. Taken together as a genre of folklore, folk illusions show that people, starting from a young age, possess an awareness of the illusory tendencies of perceptual processes as well as an awareness that the distinctions between illusion and reality are always communally formed.

Visual illusions are compelling phenomena that draw attention to the brain's capacity to construct our perceptual world. The Compendium is a collection of over 100 chapters on visual illusions, written by the illusion creators or by vision scientists who have investigated mechanisms underlying the phenomena. --
