My Answer: It comes from Rosh de Arich Anpin in the form of the Surrounding Light, for the Light of The Zohar is the Light of Infinity, the upper shining. This Light does not “come to us,” but rather shines upon us “from afar” and brings us back to the Source. It shines upon us through all the worlds that reduce it, and illuminates our desires that are opposite to it.
This is not the “direct” system of connection based on the screens and the Inner Light received, whereby the Light is revealed to the measure of one’s ability to bestow. Rather, since I don’t yet have the screen, the Light acts upon me from afar, and not to the measure to which I can receive for the sake of bestowal, but in the measure I can heal myself with its help.
Sometimes a person comes to a doctor who tells him: “What can I do? You need a very strong medicine, but your body won’t be able to endure it.” It happens with older people or with people who were seriously hurt. The cure exists but one’s body is too weak to take it; it can’t digest it. It may harm a person rather than help him.
The same applies in regard to the Surrounding Light, which acts upon me only to the extent to which it can heal me, that is, to the extent that I can endure it. This is because I receive the Light, the property of bestowal, as poison, as death to my egoism.
