There have been many theories throughout the ages regarding microcosm and macrocosm. To put it simply: smaller to larger…this is the way of life.
So if you want to witness the world being a better place on any level…environment, government, employment, redevelopment, etc. you must become that, which you wish to witness become the way of life.
Think of self as the microcosm and life as the macrocosm.
Mirror within you what you want to see outside of you, microcosm to macrocosm, this is the way of life.
