Since no one is participating yet, I don’t want to push you too far in a particular direction. But I am curious whether you have been working with the exercise I suggested: to see appearance as (essentially) light manifestion.
In doing this myself off and on during the day, I find that I quite naturally start to apply it to ‘appearances’ other than those coming in through the eyes; for instance, the sensation of sitting. This may seem far removed from light, but it makes sense to me to take light and seeing as the model from which our understanding of other senses and their operation derive.
