The difference between the will to receive that is in Kedusha [holiness] and the will to receive that is in the Sitra Achra [other side] is that in Kedusha, we use only the part of the desire we can aim in order to bestow. The part that works in order to receive is not in Kedusha. Naturally, we cannot say that the will to receive in order to receive will be corrected because it has no contact with Kedusha, so how can one correct that which he does not have?
In the Sitra Achra, there is the will to receive in order to receive. However, how can it be corrected, since light of Kedusha cannot reach there because the Kelim [vessels] drew away from the abundance and are regarded as a space that is vacant of the light of abundance. Thus, how can there be correction, since correcting these Kelim requires light and abundance, for the lights correct the Kelim, and here, where they have no light, who will correct them?
Therefore, man was created so that until he is thirteen, he acquires vessels of reception that work in order to receive. But when he still does not have light, he acquires Kelim that separate him from the Kedusha. After thirteen years, when he begins to work with the point in the heart, and observes Torah and Mitzvot [commandments] with the aim to bestow, he is rewarded with some degree of Kedusha. At that time, he can be begin to correct the Kelim he has acquired from the Sitra Achra.
