It makes perfect sense to an advaitist.
do you mean solipsism makes sense for an advaitist??
what I also don't quite get is, let's take Ramana Maharshi or Nisargadatta Maharaj for an example, they are enlightened, they are in the state of brahman, I know we all are Brahman but I hope you get what I mean, they are liberated, but then I am still under Maya, if Brahman is only one how can that be, that Brahman is still entangled in Maya.
Ramana uses the pot, water, reflection theory to explain it, where he says that the reflection disappears not the sun(Brahman), but that doesn't quite satisfy me
