Too much possession leads to excessive fear. By too great a possession, we also mean our life. If we claim our lives too much, we live in pain and fear. Our life could be taken away from us. Our life could be ruined.
Fear diminishes when we realize that our life is not so much our possession. We can leave it to itself in many ways. Just as we could give up our other possessions and leave them to themselves. The less we insist on our possessions and think we have to control and preserve them, the more painless life will be for us.
