"The universe, Light and Self are one. Subject, object and means of knowledge necessarily attend each act of perception and make cognitive awareness possible. Manifested by the creative power of the Great Light, they are always present together whenever anything is perceived objectively, and so embrace, the entire universe in their nature." - Mark Dyczkowski, The Doctrine of Vibration
"Nothing perceived is independent of perception and perception differs not from the perceiver, therefore the universe is nothing but the perceiver" - Abhinavagupta
