Self-knowledge increases our capacity of creative power. Ignorance diminishes it. We are always creating but how intensely we experience life depends on how much energy we can embody within our vessel. The more awakened we are, the more we can consciously direct this energy towards what we desire and prevent it scattering to subconscious processes. Productivity.. but what are we going to produce? What we focus on; our energy flows towards. And a relatively more conscious being can better direct greater energy towards wherever they focus, affecting more change, hence being more productive.
Self-knowledge is gained by living as awareness. Awareness is the basis for all evolution in understanding. Because, everything already exists, we are already everything we ever need or seek to be. It is just a matter of awakening to this from a lesser evolved understanding that we have created our expression to be. Underneath it all, we are the creator.
Awakened or enlightened people can affect more peace/love/evolution in the world. Their light shines brighter because they have become aware of it and have been focusing on it and hence it has become a reality through them into this world. But underneath it all, it is the same light, same consciousness, always one. So, as consciousness, how much productive you wish to create yourself as? How much life you wish to capture as your expression? There are no limits. Look at the Sun for example. Or to a galaxy. Who is creating them? Can it be different than who is creating your human self?
