It is called emanated light for the reason written here: …for it seems like a light that was newly generated: There was no need for the essence of the light to be generated as a new creation since it existed already in Eyn Sof. The innovation was that it should exist in the form of visible light. This is because whenever a given subject enters a new state different from its initial state, this may legitimately be called an innovation in its mode of being. In this case, a new state came into being: a state in which the light was visible – which was not its initial state. If so, this is light in a new state of existence. For although in its essence it is the same as it was at first, the state of the light as visible was an innovation, and this is what is meant by emanated light.
