Is There a Need for Non Duality?

Non duality comes about because of this Uncaused effect that duality is producing where we seem to have forgotten a lot of stuff. So non duality is just a negation of that's which is giving a reality to that Which has been that that we could forget. Yeah, which is an impossibility so I Just love the message of non duality because it became the last answer here and I haven't been moved to look for any other answers.
