Look at an object or listen to a sound: that object or sound is your mind. The world is your mind.
This is not crude idealism. No claim is made about the status of one domain over another; the world is no less real than it appears to a materialist. The proposal is that material reality and mental experience are the same thing, not two sides of a coin or two expressions of a deeper underlying reality. They are co-existent and identical.
They form, as it were, a fractured unity.
