664. Feeling the Sin Increases the Light
“Had Israel not sinned, there would be only the book of Torah in them.” This means that by feeling that they were sinners, they “cried out to the Lord” to save them, and any help is through the light of Torah.
It follows that every sin that they felt and for which they asked for help always adds the light of Torah from above. This means that the illumination increased for them by feeling that they had sins within them. Instead, one who does not feel a sin, does not need the help of the Creator and naturally does not have proliferation in the Torah, as he does not need the Torah to help him.
