Answer: Salt represents Malchut and water represents Bina. The connection between Malchut and Bina, i.e., the ascent of Malchut to Bina or the descent of Bina to Malchut, generates life. This is the difference between our life and the upper life.
Salt water is Bina that received Malchut’s special attributes. There is a greater amount of salt water on the surface of the earth and very little fresh water. Most of the fresh water is desalted water that goes through filters and is evaporated, etc. There are also many different systems that balance the attribute of Bina and the attribute of Malchut.
Question: In geographical Israel, there is the freshwater lake Kinneret (Sea of Galilee) and the saltwater Dead Sea.
Answer: The two lakes are total opposites. The Kinneret is fed by water descending from above, from Mt. Hermon, from melting snow and from rainwater.
The Dead Sea is the lowest point in the world, which is a depression in the ground completely covered by salt. The sea raises the salt in the earth and even the fresh water that comes from the Sea of Galilee becomes salty. The source of the salt water in the Dead Sea is different from the source that fills the seas and the oceans. This is a very special physics of this particular geographical location.
