Prisms

Our physical body is a representation of a prism. A prism is something that will take in light (not just visible, but truth and reality) and
transform it, then express it in a different way. The prism not only represents our physical form but the boundaries of our morality.
Our physical form is the living expression of this light.
(Notice what's being reflected out of the prism is not the same white light that is being taken in.) It becomes more complex. It's the same light, but expressed in a variety of different ways.
Similar to an instrument such as a guitar or piano etc, harmonies are being played through them, just as the universe plays through us.
We are the universe experiencing itself.
Through our ears, the universe is listening to its harmonies. Through our eyes, the universe is perceiving itself. We are the witnesses through which the universe becomes conscious of its glory, of its magnificence.
You can also think of this light we take in and reflect out, as our soul. Our true self, infinity. We are not separate from this. When we experience so called "death", When the structure of the prism decays, this light within the prism will transcend, it cannot be created or destroyed. Therefore we are eternal beings having a physical experience.
