Zohar, Chapter “BaHar (On Mount Sinai),” Item 66: …there are two creations in man, creation for good and creation for bad. With the Torah, he separates them and the Creator gives him a soul from Him, to dominate over both—the one that is good and light, the next world, and the one that is evil and dark, this world—as it is written, “And He blew into his nostrils the breath of life.”
Our entire reality stems from the separation between darkness and light when we can truly “filter” the qualities that pertain to this world and to the world to come. We begin to build ourselves through discernments, by distinguishing the qualities for the sake of bestowal and those for the sake of reception.
All that we study in our world is our animal existence, meaning our nature. Why animal? This is because an animal doesn’t grow, but always remains at the same level with respect to its perception.
Therefore, until we begin to use the Light so as to build ourselves, by distinguishing the bestowing qualities from those of reception, until we amass these bestowing qualities, desiring to dwell in them, and build ourselves out of them, we exist only in this world.
Just as drops of semen begin to form into an embryo in the mother’s womb, so we must try to utilize the group, the environment, the study, the intentions, and various actions to continually add and accumulate the qualities of bestowal within. This is how a spiritual body will be formed.
Every time we reveal yet another part in bestowal and wish to gather them all together, this is called our next reincarnation. Indeed, we see our new life every time and a new opportunity to keep gathering and adding to us the qualities of the human level that are similar to bestowal and the Creator (the word “man” in Hebrew is “Adam” which is from “Edome,” similar).
