Essentially, if you are not resisting materialism, you are being manipulated by stuff. The reason for this is that materialism is like a one-way conduit through which someone else controls you. Someone passes stuff and ideas about stuff through the conduit of materialism and, like it or not, you do their bidding.Joy is a conduit, too. Many things both material and incorporeal pass through the conduit of joy. It also controls you. Although, joy operates in both directions; you and someone else can send stuff through. It’s a lasting pleasure to lose control of yourself on account of joy. It's being manipulated by love.
