Honestly, To me this song has spiritual meaning. That does not mean that it was written to have spiritual meaning. To me this song basically means: Striving for worldly things will leave you empty. In this song "I", whomever that may be, finds himself with everything the world has to offer. (Money and earthly power) He has no worries. Until he realizes that money and power don't really matter in the end. All this money and power that he once had have failed him and left him even more empty than he was in the beginning. So to sum this all up, here is my advice - Don't let money or power take over your life. They may bring you happiness for a short while, but it's only temporary. Invest your time in relationships - Most importantly your relationship with God.
