Question: If we take any letter from the Hebrew alphabet, are its components a point and two lines? Are there no other forms?
Answer: A point and horizontal and vertical lines create a wide variety of combinations between the two forces that create everything that we can see, feel, grasp, and sense, everything that exists, not only in our world, but in all the worlds.
Question: Did the First Man (Adam HaRishon) feel the horizontal force as the power of bestowal and the vertical force as the power of reception, meaning, did he feel these two forces within himself?
Answer: Certainly, and therefore he discovered them. Nothing exists in the world except for these two forces. Plus and minus, electron and positron, and everything else, these are derived from the same two forces.
