The Bible says that when you think first about your profit, your profit leaves you.
In other words, when you think first about your material things and not about the people that are close to you, then at end of the road, even with all of the things that you might gather (even if it’s billions of dollars), you’ll have no fulfillment.
The reason for this is that our life is not built on the fulfillment garnered from physicality. Our life is built on the fulfillment we feel as a result of giving to others, sharing with others, helping others.
The life-energy that we all seek flows to us through friends and community we have nurtured, through love that is real and pure, through children, through simplicity, and inevitably through spiritual growth. The Light from these things isn’t extinguished when our body leaves us; it is a part of our immortal essence.
