Are you quoting Nathaniel Merrit - or yourself perhaps? It sounds a bit New Age for me.
I see I forgot to add the author. No, it's a quote by the German writer Hermann Hesse. His point, I think, is that a traditional dualistic belief (JWs are a very good example) prevents humans from seeing the other half. Leaving Jehovah, therefore, means gaining a broader perspective instead of losing a focused one (unless you feel good with it).
