Editing Ohr Ein Sof (section)

==== Gilui V'Lo Hispashtus (Revelation, Not Spreading) ====
Ohr Ein Sof is not an expansion like the light of the sun that spreads outside its source - the sun's sphere, but rather it is a revelation of the essence. This means its illumination is not through leaving its source but through revealing the essence. For example, like a person opening a box containing diamonds, where the revelation of the diamonds occurs in their place, not through their expansion.

The reason for this difference is that sunlight, being physical light, occupies space and therefore its illumination spreads from place to place. This is unlike spiritual light, which is the true light where expansion and contraction are not applicable. This is one of the reasons why Kabbalists called divine revelation by the name "light."

This characteristic is one of the reasons why light is called a "name," because even though a name exists for others and not for itself (like light that illuminates for others), it is not an emanation that leaves the person but remains connected to him - when someone calls his name, they are calling to the person himself.

The difference between them is in several details:

* '''In place''': While expansion means revelation in a new place where the source, the essence of light, is not present (like water spreading from place to place), the 'revelation' of light means that in the same place where the essence is, there the light is revealed.
* '''In existence''': Expanding light is a reality because it adds something that was not in the essence and its source. It brings it to a place where it was not inherently present (which itself proves that it is a reality even before it expanded). In contrast, 'Ohr Ein Sof' is about 'revelation' that does not add anything to the essence, because the concept of revelation is that 'the essence reveals itself' (in its place).
* '''In its existence without revelation''': Expanding light illuminates by reaching a place, therefore when there is something concealing that prevents the light from reaching the place, the light does not exist at all. This is unlike revealing light - since the essence is present everywhere, but after tzimtzum it does not illuminate but exists in concealment, it is still present there.
