Here we are agreeing with what Plato said in one way, that reality is an idea, a universalised consciousness. But, nobody can swallow this hard truth. People will not understand what you mean by saying that the universe is an idea. A little education along these lines is not enough. People will think that you are talking nonsense, though it is the fact.
Thought is chit-sat.
That is all. All the solidity of the Rocky Mountains in dream will melt into airy nothing when you wake up. That will happen to you in regard to this world also. All these things will melt into one, single, thought call it God, if you so like. This is what the Veda says, this is what the Upanishads say, this is what the Gita says, this is what prophets have said, this is what any religion will finally proclaim.
