is not necessary to negate the external world. We needn’t say that it doesn’t exist. It is enough to see through the false assumptions that we “look at” an external world while simultaneously (and equally erroneously) believing that a separate visual world lurks somewhere inside our skull despite it being seemingly imperceptible. What’s important is to grasp that the two-world assumption is illusory. That the world we see is the visual perception located in our head.
