Returning the matter at hand, for the lights loom over the letters and include all the possible sepicific aspects contained in each letter, per my memory. However, only a indivual contained light is apparent to the soul peering at the letters, similar to a coal. With the effort to understand, read over and over and redouble the effort to understand, the lights begin dance in the soul as a flame ignites via a coal. This is all encapsulated in what the Tanna (Pirkei Avot 5:22) says: "Turn it over and [again] turn it over, for all is therein..." - that it is necessary to examine and reexamine words of Torah until the lights are revealed as with revealing the flame within the coal.
