Goal
We will attempt to experience the illusion of a separate material world directly.
Prerequisites
Same as that for introspection - 1. Note that the word "World" is used with a philosophical meaning. Whatever that surrounds us here and now. So its not the globe or the "cruel world".
This is probably the easiest of all introspections. You don't need to keep the mind out of the way. It stops on its own. But it is always good to start with a clear mind.
Question
Ask yourself - What is this world made of?
