Accumulation as such is a concept of a human who illusionary perceives himself as an object.
As smth separated from All that Is.
It actually creates more poverty even for the person itself, than prosperity.
A true-er view would be to view things as flows/processes. For example, when you give someone money, you see it as "supporting the flow of money directed towards you". You are not left with less money, you stir up the flow.
When you try this on small spending amounts that do not matter much to you, you will see that the amount of money you gave away came back to you very soon. After that you can try that on a slightly bigger scale until it integrates in you completely.
This is not about money, objects and all that. This is about the nature of things. Apply this to all possible aspects and a greater view on reality will start opening up.
And you will live in a more prosperous world where everyone gets as much as they need without competition or fight. Eventually the idea of money will not be needed.
