Answer: The Dead Sea (in Hebrew, the Sea of Salt) is the lowest point on earth. It has to be salty since salt is the lowest, most essential, non-deteriorating food substance.
What do we consume in its natural form from nature? Water and salt. Water and salt are the material of the Dead Sea.
Malchut is the embodiment of all the still nature , so there is actually no life in the Dead Sea except for some bacteria. But today the world is in a state that bacteria exist in different forms and we may certainly soon find out that they have also been discovered on Mars.
But ordinary life cannot exist in salt because it is a preservative that fixes all the attributes. It doesn’t allow anything to develop. It is a pure attribute of Malchut. The water of the Dead Sea, which means the attribute of Bina, is intended only for the salt to grow and symbolizes the use of the slightest altruistic awakenings for the sake of the ego. Using the Creator for yourself, this is the addition of water to the salt.
