What is light? No on knows.
Particles, waves, energy?
Light reflects. It also refracts: passes through and bends.
A leaf absorbs all colors and reflects green. An apple absorbs all colors and reflects red.
Everything the eye can see is a reflection of light, and in the absence of light the eye sees nothing. The same is true for our hearts. Everything the heart can see is a reflection of light and in the absence of light the heart can see nothing.
When a heart blossoms it turns toward the light just as a flower turns to the sun. We receive Divine light, and we can spiritually see. Awaken. We see the light in ourselves and the light in our neighbors. We feel the light we absorb, we see the light we reflect, the light others reflect, and the source of light we share.
