We typically take it for granted that we know what we’re doing and thinking all the time so can simply make changes at will. But in reality, most of these processes are habits that run unconsciously on autopilot with much less awareness and clarity of ourselves in action that we believe.
For instance, as you are washing the dishes what are you thinking about? What are you feeling? What are you sensing? How are you moving?
Observations of thoughts, feelings, sensations, and movement (and the connections between these unified processes) can enhances your personal knowledge and accuracy of your experience in action.
Practice like this can help you see reality more clearly - and help you see and understand yourself and your actions more accurately.
To know how exactly you do what you do is a skill that can be developed. One that can lead to a much richer self-representation, and maybe even a much richer life experience.
