Your post, Jack, makes it easier to relax: ..”at the same time, there is not any need to structure in terms of high and low…”.
I thought about bright lights. Here in Germany spring is beginning. Soemtimes the light is new, bright and fresh. I went through a beech-forest. The very young leafs reflected the light of the sun: it was a very intense light green. In another situation after a rain in an fir-forest, the raindrops hang on the needles of the trees and the sun began to shine: there were many very bright lights in many colours. And I´m surprised: the little, sometimes weak candle light (of an exercise) begins to shine. And it seems to me, that in holy prayers and sayings there are connections to light: For example in the beginning of Samantabhadras Prayer of Enlightened Practice (“In all the world of the ten directions…) or in the christian bible, when St. John (I don´t know the correct english name) tells of seeng to the ground of the sea, when water and fire are mixed..
I worked with seeing light also in my resistance and in my – sometimes – bad mood. At once I felt a reaction in my belly, a warm moving – my reactions and mood changed.
At the same time I asked, what is happening? It seemed that I were in this moment on a meta level. (I don´t know how to describe it in a more correct way) .Was it a running away from my bad feelings (or in other situations: the feelings of another person)? It was another quality than usual, when I touch the feelings of a person, and I stayed (when I visualized light) in contact with my surroundings. Does this mean:” Not caught up”(so much) “in the flow of events”? (KTS, p. 491)
And with the readings: My mind does not understand what is told, he lives on a “low” level. But at the same time:Â I feel a reaction in my belly, he seems to understand something. Is it possible, that – in my situation of understanding – my body grasps what my mind is not able to understand?
 I have deep respect for the readings.
