Answer: We are all in a global, integral, limited system of nature which is interconnected into a single “sphere” that you cannot break out of. You are obligated to be in this sphere and to be connected with others very precisely. There’s nothing more or less than this.
Therefore, when you buy a car that’s twice as expensive, you become a cancerous cell because in that case you are not buying it to lead a normal life and to serve others but in order to “snatch another bite.” The more you “consume” beyond the necessity, the more of a malignant tumor you become.
The common organism is built ideally: Every person in it has to receive the vital necessities and in every other regard to think only about others. The Creator made the desire and its fulfillment. So why are you suddenly taking more than your due?
All desires are united into one. The Light fills them and gives them life in the single form. But suddenly you are “pulling the blanket to your side,” wishing for more. As a result, your excess will definitely come at someone else’s expense.
Today we are being shown this clearly: A billion people are at the brink of starvation, and in the meantime the earth’s resources are reaching an end. Soon we will use them up and will be left with nothing.
We are reaching the end with all of our consumerist production. And what will happen next?
Therefore, if you want to reach life within the boundaries of vital necessity against your will, that’s what will happen. Everything is finite, limited, and used up. Everything has an end, and it’s getting closer.
