Baba explained on the nature of Noor – Divine Effulgence:

The Noor of God is infinite. It is different from your electric power. All types of powers like electric, atomic, heat, light, et cetera, are only small branches of God's Noor. Noor is not light; it is far more than that. To explain it, we will use a simile. If ten million suns are put together, the coolness of these would only be a fraction of the coolness of Noor. From Noor the sun, stars, moons, planets derive their light. Noor is infinite; it cannot be divided. And so suns, stars, moons, planets must be contained in it.

It is difficult to explain this since you have had no experience of it. For example, suppose Cowas has had wine, and you (Hoshang) have not. However much he may explain what intoxication is, you will not be able to grasp it; meaning, without experience you cannot know what intoxication is.
