Learn to look without imagination, to listen without distortion: that is all. Stop attributing names and shapes to the essentially nameless and formless, realize that every mode of perception is subjective, that what is seen or heard, touched or smelt, felt or thought, expected or imagined, is in the mind and not in reality, and you will experience peace and freedom from fear.
(On page 96 of The Wisdom of Nisargadatta (1992) by Robert Powell, the sage Nisargadatta Maharaj says the above)
All exists in the mind; even the body is an integration in the mind of a vast number of sensory perceptions, each perception also a mental state ... Both mind and body are intermittent states. The sum total of these flashes creates the illusion of existence.
(p. 201 of I Am That (1984))
A net of Jewels (1996), Ramesh Balsekar says,
Other than Consciousness nothing exists. Whatever you see is your own reflection. It is only through ignorance of your true nature that the universe appears to exist. One who understands with conviction that the universe is nothing but an illusion becomes free of it.
"A nation is a society united by delusions about its ancestry and by common hatred of its neighbors."
