The nature of god is usually a deeply personal and subjective thing. I could offer a lot of opinions on it, but I suppose I could more simply say that my view of Monad is Nature. Not in the limited "mother nature" context, but in a more "the universe has a natural flow" context. Basic analysis of the physical evolution of nature seems to agree with this context, because of the cycles, evolution, and various other things. A forest seems chaotic until the science behind it is understood, and then its growth can be analyzed and even predicted. As below, so above.
Such ideology isn't really that different from the chaos views that have been discussed here, except that I feel there to be a certain flow within the chaos.
And as for singular purpose. Well, let me just address that as simply as I can. I very strongly believe in fate, and as my understanding of this concept and my working with it has deepened over the years, my belief in this has only grown. It's a rather specific topic that is, in my opinion, very largely misunderstood.
Now, within this idea of fate, which is itself completely independent of any deity (for in most mythologies, even the gods are bound by fate), there is no such thing as "singular purpose." There may certainly be specific things that one should achieve in a given life, but there is never just one of those things. When I practiced divination to the point of obsession, I learned a lot about my own fate, my own "purpose," as well as those of others. Not once did I ever observe, in anyone's fate, a "singular" purpose. Life is just life. Everyone has things they are good at naturally, things they should do. Some people are great parents, some people are great martial artists, some people are great magicians, some people are great teachers, some people suck at teaching but are great researchers. Doing those things which one is good at naturally usually fulfills ones sense of purpose.
Truly, it is that simple. You do not need religion or a deity to give you purpose, because really, they can't. Your purpose is yours to discover, or to create. Your life is yours to live.
One of my favorite quotes from Thomas Jefferson comes from when he spoke against the concept of Divine Salvation: "Every mans salvation is in his own hands."
No god is responsible for your fate, for your purpose, for your life, nor anything else that is yours. Regardless of theology, everyone is ultimately responsible for themselves.
