There are certain things in life that one might call the "unlimited ones." I believe some Buddhist traditions have something like this in certain teachings.
I would call joy and love two of the unlimited ones. We don't lose any of it by giving it away. In fact, the more we give it away, the more it grows in us.
Simply put, that's what I was thinking about when I came up with the phrase for today.
Share your love. Share your joy. Others will benefit. You will benefit.
