Everything is for man.
The Book of Zohar with the Sulam [Ladder] commentary, Toldot, Item 2
The value of one person from the Speaking equalizes with the value of all the forces in the Vegetative and the Animate in the whole of reality at that time, and in all the past generations. This is so because its power encompasses them and contains them within its own self, along with all their forces.
Baal HaSulam,
“Introduction to the Book, Panim Meirot uMasbirot,” Item 3
And we must not ponder the state of other beings in the world but man, since man is the center of Creation. And all other creatures do not have any value of their own but to the extent that they help man achieve his perfection. Hence, they rise and fall with him without any consideration of themselves.
Baal HaSulam,
“Introduction to The Book of Zohar,” Item 18
And the most important thing in this whole diverse reality is the sensation given to the animals—that each of them feels its own existence. And the most important sensation is the noetic sensation, given to man alone, by which one also feels what is in one’s other—the pains and comforts. Hence, it is certain that if the Creator has a purpose in this Creation, its subject is man. It is said about him, “All of the Lord’s works are for him.”
Baal HaSulam,
“The Teaching of the Kabbalah and Its Essence”
This purpose of Creation does not apply to the still and the great spheres, such as the earth, the moon, or the sun, however luminous they may be, and not to the vegetative or the animate, for they lack the sensation of others, even from among their own species. Therefore, how can the sensation of the Godly and His bestowal apply to them?
Humankind alone, having been prepared with the sensation of others of the same species, who are similar to them, after delving in Torah and Mitzvot, when they invert their will to receive to a will to bestow, and come to equivalence of form with his Maker, they receive all the degrees that have been prepared for them in the Upper Worlds, called NRNHY. By that they become qualified to receive the purpose of the Thought of Creation. After all, the purpose of the creation of all the worlds was for man alone.
Baal HaSulam, “Introduction to The Book of Zohar,” Item 39
