First, I've taught for a long time that the material is the hard form of the spiritual.
Think about it.
If money, cars, homes, etc are not spiritual, (or at least also spiritual), then what is?
I had a spiritual teacher decades ago who told me, "As soon as you see God in the very thing you condemn, fear or judge, in that moment you will awaken."
For me, money is simply a tool.
Recently I used it to buy a new car, but I also used it to give funds to build a school in Taiwan, fix a hospital in Mexico, help a young man who just graduated, help fund a movement to end homelessness, help another friend with the IRS, and help fund a shelter for domestic help.
Money let me do all that.
But when you feel money is evil, or rich people are bad, you have closed off your heart, disconnected with the Divine flow, and become very un-spiritual.
Our purpose in life is to awaken. To do that, we have to drop judgments about everything we fear -- including money.
When you can say, "Money is the root of all spirituality," you will begin to understand true spirituality.
In fact, a spiritual teacher I admire (Arnold Patent) said, "The sole purpose of money is to express appreciation."
I *love* that quote.
It helps point you in the direction of understanding money as a tool for good - a spiritual tool, at that.
