Answer: In the spiritual world, there is no question of “where?” The ocean is. It is about certain attributes, many forces that are interconnected.
Water symbolizes the attribute of bestowal (Bina), in which different animals (Malchut) appear. This means that Malchut rises to Bina and the mutual cooperation between them brings it life, by obliging Bina to turn to Keter and receive Light.
The Light spreads in Bina and performs certain actions in it, and thus marine life is created in the seas, in rivers, etc. Everything stems from Bina and then gradually descends to Malchut, which means that all the creatures gradually come out of the water and unto the land and begin to multiply, to spread, and to live on it.
We learn about the mutual cooperation between Bina and Malchut as Tzimtzum Bet (the second restriction).
The mutual cooperation of the forces creates this picture of our world until a person reaches spiritual attainment and then he looks at the world and sees which forces are behind the earthly objects, how they manage the world, and how certain spiritual attributes affect the upper roots.
Question: Why are there mountains, plains, and valleys in our world? What is their spiritual root?
Answer: According to the wisdom of Kabbalah everything stems from the attributes of two forces: Malchut and Bina or the Light of Hochma and the Light of Hassadim, the attributes of reception and bestowal. The mutual states that are created between them reflect and have such implications on our world.
There is no need for anything else but these two forces. Together the attributes of bestowal and receiving create the whole variety of attributes, the types of characters, and the objects on all the levels of nature: still, vegetative, animate, and speaking.
There is nothing in nature but these two opposite forces: an electron and a positron, a plus and a minus.
