This song describes 2 ways of life. Neither look very attractive as they progress towards stony cold meanings and lifeless endings. This is the monism/duality philosophy at work, it creates a perfect paradox. For only when humans see limitations will they strive to change this by creating new meanings. When we create new meanings (which happens inside ourselves), a new outer world is born for us to enjoy. So this song is all about looking outside in the physical world to remind us to look inside in the inner (spiritual world) to remember that we don't in fact have any limitations.
