The Guiding Light is the Force in the Universe that Guides all the other Forces in it.

This question is like asking what God is.

All that is good in this Universe is good because it is being Guided by the Guiding Light.

The Angels are all bond by the Guiding Light; even Satan can not go against the will of the Guiding Light; it is Heaven, and Hell; this may seem light a contradiction since Heaven is Light, and Hell is Darkness; but there can be no Darkness without the Light, nor Light without the Darkness; the two are flip sides of a coin; like Matter, and Antimatter they exist together.

The main distinction that the Light Wizzard wants you to remember is that when we are talking about the Guiding Light; we are talking about the whole Universe at the same time; its source is the Universe, it is everywhere, it is everything, it is the source; when all other lights fail, the Guiding Light will always illuminate you.

Without the Guiding Light, life could not exist.
