Money is a powerful generator of unwholiness. This is overall unavoidable because our egos cannot act with wholeness. It's also a cause of all kinds of conflicts and a lack of subtle energy. Money is made of subtle energy, as all things are, but money is itself a crude form of energy.
Let's say for example that I have the choice between a) earn $1,000 more, b) $1,000 less or c) remain having the same income. The habitual choice of the ego is to choose a) without thinking twice about it. Is that a choice of wholeness? The answer is: the ego doesn't know. Because as Stephen Wolfram has explained, even many simple processes are computationally irreducible, which means it's impossible to fully predict the future.https://www.youtube.com/watch?v=6hCkO0-MhEs
So the ego does NOT know whether choice a, b or c is an act of wholeness which means beneficial for society as a whole. What kind of choice does my neighbor want me to make? If he or she is also acting from the ego, then there is the same unknowingness in him or her about what choice I should make, even from the perspective of benefiting the neighbor. To act out of greed and choose choice a might be wholeness. But acting with selflessness and choose b might be wholeness. Or doing nothing, choice c, might result in wholeness. It depends on the particular situation and how it fits within the whole. As an ego therefore I might as well choose choice a and grab the money, because then it benefits me in monetary amount terms.
If I was aware of the wholeness of the situation, I might choose a too, or c or even b depending on what is whole action, meaning beneficial for both myself and others seen from the bigger picture.
When the physical body has wholeness there is health. And since money generally fails to achieve wholeness when we act from our egos, it causes disease in society, in the "body" of humanity. Money itself is just a tool. The cause of the unwholiness is how our egos use money.
What, then, to do, to cause wholeness in our life? One approach is: don't let your left hand know what your right hand does neither when you give NOR when you take. Then subtle energy has a possibility to flow into our choices and actions, which heals our psyche and our physical body. We can start with small things such when taking or giving $1 and still use our egos for bigger choices like in the example of $1,000 and just grab the money as usual. In this way the idea can be tested experimentally in a gradual manner.
