As it stands, I plan on writing a blog about the idea of light in TSK. Here are preliminary notes for this.
Love of knowledge- p.35 light of knowledge/darkness of wanting
363, darkness of the “ness”
Dynamics of Time and Space- light of knowledge, xxvii
64- clarity inseparable from light
65- “thoughts awaken to the lightness of their arising”
105- this circle of light/limitations outside of knowledge
114- claims as knowledge express lightness, that is not bound by the “witness”
125- darkness of mental constriction, lacking light
134-5- unknown time and light/darkness, the play of known and unknown
138- awareness is the light
154- the lightness of our being, lightness let loose, we fuse with light
164- what does light reveal if there are no obstacles?
