"Whom Hashem has given me"
Rabbi Shimon first describes how the Torah (zeh) is set before the children of Yisrael. Rabbi Rav Nachman then explains the difference between zeh and zot, pointing out that the Torah is referred to as "Tor," in the feminine, which is a name of a dove - meaning "the time of the singing bird is come," sung by the Levites, which is the secret of the female aspect of the Torah - the turtle being the secret of the male aspect. Rabbi Rav Nachman then explains that Hei (holiness) ה is more important than Aleph א. Next, Rabbi Aba tells us how the measurement of the span of God is 670 years, from heaven to earth. Rabbi Aba concludes by explaining why the Torah is called Zeh.
All reality consists of both male and female energies. When these two polar opposites are united, Light flows and shines upon supernal and corporeal worlds. Our physical world of Malchut embodies female energy, while the Upper Realm of Zeir Anpin corresponds to male. This passage conjoins the two worlds, allowing the resplendent Light of The Creator to vanquish all forms of darkness dwelling in our midst.
