Pure light is all colors.
Therefore, it has no hue.
Only when singleness is scattered
Does color appear.

When we see pure sunlight streaming down upon us, it is a pure radiance so bright that we can discern neither details nor hues from its source. But when light strikes the gossamer wings of a dragonfly, or when it shines through misty rain, or even when it shines on the surface of our skin, it is polarized into millions of tiny rainbows. The world explodes with color because all the myriad surfaces and textures fracture the light into innumerable, overlapping dimensions.

The same is true of Tao. In its pure state, it embodies everything. Thus, it shows nothing. Just as pure light has all colors yet shows no color, so too is all existence initially latent and without differentiation in Tao. Only when Tao enters our world does it explode into myriad things. We say that everything owes its existence to Tao. But really, these things are only refractions of the great Tao.

Colored light, when mixed together, becomes pure, bright light again. That is why those who follow Tao constantly speak of returning. They unify all areas of their lives and unify all distinctions into a whole. There cannot be diversity within unity. When our consciousness rejoins the true Tao, there is only brightness, and all color disappears.
