The light in an individual is not a shard but rather what is reflected off of the shard. In science, light is called a photon; as in a particle. Here we could give it an added part; that of sentience. So light here would be photo-sentience! What passes as light in an individual is sometimes referred to as a spark of thought. It could also be called the photonic sentience cognito effect: as light is transmitted through thought on a self-aware geometry. The issue of the light is the points on this geometry with thought being the shape that the points construct. The level of sentience involves the topology that underlies the type of thought being displayed. All very concrete and scientific, however, is the light itself created by sentience? No. Light itself is pulsed; just as photons can be particles or waves, the same is true of photo-sentience. Light is of spiritual construct. Merged with mind there is sentience. Without mind, it is but raw emotion. The amplification is a part of behaviour. Behaviour is the algebraic geometry of photonic sentience cognito effect at a given time. This is the Light in an individual!
