Question: In The Study of the Ten Sefirot it says that a person who corrects himself begins to “illuminate,” what is this action?
Answer: A person begins to “illuminate” when his vessels begin to bestow. This illumination is already a self-movement that only a human being can perform. No other creature on the levels of the still, vegetative, and animate nature can illuminate, since it doesn’t connect with the Creator in any way; it doesn’t perform independent actions of bestowal like the Light.
The simple Light fills all of creation and thus illuminates. A “human being,” however, is a person who spurs himself towards the Light, and the Light illuminates because it has more intensity than the natural intensity it has when it arrives. A person becomes an amplifier for the Light: He illuminates by himself thanks to the Light that fills him.
There is an addition to the Light created by the person! It is because he has overcome his desire to receive by turning all his desire to receive into fuel, into a combustible material. When the Light comes, this material begins to burn like a candle! So it says that a person illuminates.
He is called “a man of the Light.” Can he radiate the Light? He has prepared his desire to receive in such a way that it is equivalent to the Light. Now when the Light goes through his desire it is illuminated by it like a fluorescent lamp that is filled with a special gas or with phosphorus that begins to shine under the influence of the Light.
When the Light comes, the desire is impressed and begins to illuminate from inside. This is what happens to a person who identifies with the Light. It is because he doesn’t swallow the Light inside him egoistically, but wants to carry on its action. You should know that in order for you desire to begin to illuminate, you have to restrict it and to place it under the Masach (screen) so that you will not want to swallow the Light for itself, but rather will want to connect with the actions of the Light in bestowal and to draw this Light for everyone else. Then you will illuminate and be called “a man of Light”!
How intensely you illuminate is determined by your spiritual level.
