Now carefully analyse the underlying consciousness which, though abstract and apart from material objects, yet illumines them all the same. Know it to be the truth. O Sage! What is not self-luminous can only fall within the orbit of intelligence and cannot be Intelligence itself. Intelligence is that by which objects are known; it cannot be what it is if it becomes the object of knowledge. What is intelligible must always be different from Intelligence itself, or else it could not be made known by it. Intelligence in the abstract cannot admit of parts, which is the characteristic of objects. Therefore objects take on shapes. Carefully watch absolute intelligence after eliminating all else from it.
~ Tripura Rahasya; chapter XVI, verses 15-19
