The Book of Zohar. Chapter “The Fifth Commandment” (abridged)
215. The fifth Commandment. It is written: “LET THE WATERS SWARM WITH SWARMS OF LIVING CREATURES.” This verse contains three Commandments. The first is to study the Torah (as it is written, “I have created egoism and the Torah for its correction,” which is achieved only through the study of Kabbalah, which attracts Ohr Makif – the Surrounding Light), the second is to procreate and multiply (spiritually; that is to say, to develop the point in the heart to its full capacity – the soul), and the third is to remove the foreskin on the eighth day (to make the corrections under the condition of complete bestowal, cutting off from oneself the work in desires that are impossible to correct – “Lev haEven” – the heart of stone, Zivug in Sefira Yesod, and not Malchut). And it is necessary to study the Torah on all the days, at all times, in order to correct one’s soul and spirit (to search within oneself for the Creator and for a dialogue with Him every minute of one’s life).
216. Because man labors in the study of the Torah, he corrects the other holy soul, as it is written, SWARMS OF LIVING CREATURES, referring to the life-giving holy soul, Malchut. For when man does not study the Torah (the method of correction), he lacks the holy (loving and bestowing) soul and the (quality of) holiness that descends from Above (from the Creator). Yet, when he does study the Torah, he merits its Light (correction and fulfillment), just like the holy angels (he merits full equivalence to the Creator, just like the angels; the only difference is that they are mechanical creatures, whereas man attains equivalence consciously, with his desire and efforts).
217. It is written, “Angels of the Creator (people who have attained the level of the Creator Himself, and who are hence called ‘angels’) shall bless Him.” This refers to those who study the Torah (correct themselves), as they are called His angels on earth (those who have corrected their desire, while in and of themselves the angels are qualities of Bina, the Creator, bestowal). It is also written, “BIRDS SOARING OVER THE EARTH.” This refers to this world. However, in the world to come, as it is said, the Creator will make them (those who correct themselves) wings like those of an eagle so they may soar (with their corrected desires of love and bestowal) over the whole world (over their whole egoism).
218. It is written in this regard: LET BIRDS SOAR OVER THE EARTH, for the Torah, called “THE WATERS” (the quality of Bina, love and bestowal) will SWARM WITH SWARMS OF LIVING CREATURES (will be filled with the corrected souls of people) from its place of life (the desires that feel themselves, their lack of correction), called Malchut (all the created desires), and all will descend down below (the intentions “for one’s own sake” will disappear and only the pure intentions – “for the sake of others” – will remain). This is what King David referred to when he said, “THE CREATOR CREATED IN ME A PURE HEART” to study The Torah (correct oneself), and “A HOLY SPIRIT (of love and bestowal) WAS RENEWED WITHIN ME (what was contained in the Thought of Creation now became my conscious aspiration, to fulfill myself).”
