It is written in The Zohar (VaEtchanan, Item 35) about the verse, “And the eyes of both of them opened,” “In the future, it is written, ‘And I will lead the blind in a way that they do not know … for the Creator is destined to open eyes that were not wise, so they will look in the high wisdom and attain what they did not attain in this world, so they will know their Master.’”

It is written in Isaiah 42, “The deaf will hear and the blind will look and see. Who is blind but My servant, or deaf like My messenger whom I send? Who is so blind as he that is at peace, and as blind as the servant of the Lord?”

We should understand this. Does the Creator have only blind servants and deaf messengers? Could He not pick for Himself people without blemishes?

In the way of the work of the Creator, the path of truth, there are always two opposites, as is explained in several places in the Sulam [Ladder commentary on The Zohar]. Also, here we should interpret that one who can be a messenger of the Creator is precisely one who is “deaf,” since he does not want to hear slander. When a person wants to work Lishma [for Her sake], the body resists him with all kinds of arguments, and he pretends not to hear what the body tells him.

It follows that he can always be in wholeness, since the reason why one falls from one’s degree is only because he listens to slander from his body about work not in order to receive reward. It follows that he could always be in wholeness.

On the other hand, he should see that he is “blind,” meaning that he has no opening of the eyes in the Torah, since the whole Torah is the names of the Creator, yet he does not see.

At that time, he has Kelim [vessels], called “deficiencies for the light of Torah,” since he feels deficient because the whole of the Torah is concealed from him, and he feels that he is blind. Precisely he can be a servant of the Creator, meaning that the Creator will open his eyes in His Torah [law], as it is written, “Open our eyes in Your Torah.”

However, we see that there are many people who are blind because their eyes were sealed to the light of Torah, and not just anyone is rewarded with opening the eyes. Our sages said about that, “A blind is as important as the dead; the poor is as important as the dead; he who has no sons is as important as the dead.”

This means that if one considers himself “dead” when he feels that he is blind, meaning feels that by this he becomes poor in knowledge, that he has no understanding in the Torah, which is regarded as having no sons, he regards himself as though he were dead, that he has no taste in life because his eyes are sealed from the Torah. Yet, he is called “a servant of the Creator,” as it is written, “as blind as the servant of the Lord,” and he is rewarded with opening the eyes in the Torah.

This is the meaning of the words, “the deaf will hear.” It means that afterward, when he is rewarded with the light of Torah, he who was previously deaf and did not want to hear the slander of the body concerning work in order to bestow, afterward he hears, observing “And you will love the Lord your God with all your heart,” meaning with both your inclinations, since “When the Lord desires man’s ways, even his enemies make peace with him.” At that time, the body, too, agrees to the work of the Creator.
