The effect of Mars is violent, accelerating, and intensifying. Mars is the active principle, dynamic energy. If well applied, the Martian forces are constructive; if uncontrolled, they result in destruction.

Physiologically, Mars rules the muscular system, the red corpuscles, the body heat, and the combustion processes in the body, the sexual organs, the suprarenal capsules, and, together with the Sun and Jupiter, the formation of blood. From food it absorbs the iron that it transmits to the blood.

The Sun and Mars together bring vitality, initiative, and courage.

Mars also shares in the vital processes (with Jupiter and the signs of Leo, Libra, Scorpio, Sagittarius, and Virgo).

Mars also influences the motor nerves, the left half of the brain, the gall, the fibrin in the blood, the rectum, and the astral body.

According to Paracelsus, Mars rules over the polarity between the brain pole (Aries) and the sexual organs (Scorpio), that is, the beginning and end of the serpent power.

Mars further rules over the diaphragm, the left ear, the purging processes, the head and head injuries, inflammations, and surgical

treatments,

The image of Mars is male, aggressive, warlike (martial), and intensely sexual, with the so-called animal magnetism,
