There are two wolves inside each of us. This comes from many old traditions, and is often associated with Good and Evil, or compassion and self interest. When divested from this judgmental, polarizing, limitation, one may find much that is useful.
One is Spirit, Evolution, Growth, all the things we see beyond hard science, that which we know in our hearts is true. This is the realm of Spirit.
The other one is Hard Science, Classical Western Education, a materialism which says that entropy is all. All things, according to this tenet, eventually run down and decay, including the observable universe since the Big Bang.
Which one will survive? No one can serve two masters (Jesus). The one that we feed is the one that will win, within us. This simple fact evolves out of the idea that Man has Free Will.
If we rise to the occasion and grasp the day, Carpe Diem, much is attainable that seems to bely common sense materialism. It’s not the easiest path.
When one embarks upon the path of spirit one may Create Order out of Chaos.
Within this act of Creation one may awaken our connection to the larger possibilities which we may associate with the concept of God.
How real this is may be tested through empirical, pragmatic means by how well it works for us in furthering our goals. Positive results may then foster a faith in this process, strengthening the power (functionality, effectiveness) of the system.
Ideally we can take that which is useful from each wolf - not waste anything - and use that which is useful in creating a better, more inclusive world of which we are an integral part.
Namaste.
