There are certain stages in spiritual development, which are quite specific. For example, access concentration at will. One of these stages is constant control of the visual field, i.e. to always be in control of what is existing visually (and so astrally) in the mind. Now it might not always be positive or in real-time, but it becomes all conscious.
So before training, the mind just runs around and does whatever it wants. But then one learns to control it for specific periods of time. Then there is improving awareness and concentration. Each evening, the days events can be reviewed and people will generally struggle to remember what they were visualising in the morning as it was largely unconscious, but this will improve, to the definite state where one is aware, looking back throughout the just-lived day, or what one was visualising (and so the state one was in). This stage is partly due to improved recall and partly due to improved concentration, but it coincides with increased disipline, and so happiness and ‘luck’.
