Do you know why money is also called "currency"? It means "current" which is something that can flow. And it needs the flow for it to work well.
Hence we all need this "flow" in our life too in order for us to be successful and prosperous. So it is not beneficial spiritually to keep money under your closet or bed. Let it move and flow. I think it is right to say that. Do you agree?
When there is a money flow in and out through you, it creates a virtual exchanger in you which balances itself naturally and the surpluses are returned to you. Maria Callas says that is a act of law of the universe.
No flow; no currency; no positive enhancement.
