Sometimes Light, Sometimes Dark

A reflective and quiet practice this morning early. During breathing I managed to keep my mind fairly clear of debris for moderate lengths of time, and shaking due to Parkinson's was minimal.

Asanas were smooth and mindful. I learned some helpful pointers from AG Mohan's book yesterday, and kept my limbs supple rather than tensed during movement.

Sometimes during pranayama as I stare into the darkness of my closed eyes, I see light-colored patterns and fireworks on a black background. Other times I see dark shapes on a slightly lighter background. Today it was the latter. I wonder, what accounts for the difference?
