This is something I sketched up a couple of weeks ago:
Our subconscious determines our very first and immediate reaction to a given stimuli. This generates raw feelings. We cannot help but react at this level to the stimuli. Once we are aware of the stimuli, and note our immediate reaction; we then have conscious choice over how we respond to the stimuli emotionally and rationally. We also have conscious choice over what we do (or how we act) in response to that stimuli.
If we are aware, we get to choose what we feel, think and do in response to a stimuli. If we are unaware, we react without thinking (the red arrow in the diagram above). Thus we can only change our thinking and actions with awareness.
How we act, our behaviour, will likely lead to further stimuli (from the world we are interacting with). And the cycle starts again.
Our thoughts can also start the cycle. If we think X, and chose to respond to it by doing Y, we get a stimuli in reply from the world at large.
Does this make sense to you? Does this trigger any thoughts?
