Sometimes we wish we had more money to make our lives happier. But money cannot buy happiness. In the Osashizu is the following:

You might not understand easily if I speak of causality. Listen and understand the truth well. If things happen the way you wish, that is because of causality. If things do not happen the way you wish, that is also because of causality. If you all pass through life with no awareness of causality, with no awareness of causality at all, then there is no knowing what sort of causality will manifest itself. However hard you try to cause something to happen, it might not happen- such is causality. Were it possible for the power of money to make anything happen, it would be as though the one truth did not exist. Causality means that the power of money cannot cause things to happen.

Money or power cannot buy us happiness.
