Based on a Naaleh.com shiur by Rabbi Yitzchak Cohen
The Chovot Halevavot discusses the various marks of wisdom that a person can see in the world and the way Hashem is manifests in creation. He lists seven ways to see this.
The first mark is manifested in the four fundamental elements of the world: fire, water, air, and earth. In contemporary terms, these are energy, liquid, gas and solid matter. The earth is a ball, which by nature doesn’t stay stationary. Yet our world stays suspended in the middle of the universe. It is surrounded by water, above that air, and above that fire. Each element stays within its boundaries. Nature stays faithful to its Creator and doesn’t change. This shows the magnificent greatness of Hashem. David says, “You Hashem are the creator of heaven and earth, which exist eternally.” If there would be one slight deviance, the entire world would be destroyed.
The second mark is man himself. Every person is a small universe. The completion of this world is man. Without him there is no purpose. Humans are like a dot in comparison to the vast cosmos. Yet we see it is only man that can understand creation. In Tehilim David wrote, “Man is a little bit less than Hashem.” When Adam was created the angels wanted to say kadosh. They thought he was the Master of the world. Hashem is a perfectionist par excellence. He made man flawless and in whatever state he’s in his Divine Image remains.
The third mark is the amazing synthesis of soul and body. Hashem covered over spirituality with flesh and bones and formed Adam. Iyov said, “You made me as if someone poured milk into a bottle. You curdled me like cheese. Then you clothed me with bones, sinews, and ribs. You sheltered me, gave me life, favored me, and watched over my soul.”
The fourth mark is the animal kingdom which is made up of hundreds of different species. They swarm in the air, swim in water, and creep on the ground. Hashem created them all with a purpose and their daily existence is in His hands.
The fifth mark is the wisdom in the design of the plant world. There are myriad types of vegetation that have the ability to heal and provide nourishment.
The sixth mark is the wonders of Hashem that we see in industry and science. Hashem revealed different ways through which man can meet his needs in this world. Iyov said, “Who gave wisdom and understanding to the heart? Only Hashem.”
The seventh mark is the wisdom found in Torah. The Torah teaches us above and beyond what man could ever imagine or create. The oral Torah is not the work of man. The sages transmit concepts that were already accepted at Sinai. Through studying Torah a person can truly see the greatness of our Creator.
