The Mandukya Upanishad is a short, just twelve verses, description of the material manifestation and the eventual return to unmanifest form of the Universe....
Verse 25
25. That the cognition is or, has the state of being with that is, due to some cause, is fancied on seeing that is, on the strength of the presentation of the above logical reasoning; but that the cause has the state of being without a cause is fancied on seeing that is, on the strength of the actual state of things or, the reality.
According to the believers in duality their belief rests on the perception of that "other". This is the conclusion of this verse.
So, the next step is to question the reality of perceived objects, effects or an "other", Because if that "other" associated with cause and effect has no reality then cause and effect must also be unreal.
