Human Design Nine Energy Centers
Decode your BodyGraph: from the mental inspiration pressure to the root survival drive, gain insight into your innate power sources (defined) and sensitive areas that are easily conditioned by the outside world (undefined/blank).
Head Center
Pineal GlandThe Head Center is not responsible for action; it only receives the universe's downloads and inspirational pressure. About 70% of people worldwide have an undefined Head Center.
Brow Chakra / Logic Center (Ajna Center)
Pituitary GlandsIt is your information processor. People with a defined center have a fixed way of thinking; those with an undefined center have highly flexible thinking.
Throat Center
Thyroid and Parathyroid GlandsYour vocal organ and the exhaust pipe of your action engine. It governs communication, teaching, expression, and turning nothing into something.
G Center / Self Center (G Center)
Liver and Blood (Liver & Blood)The GPS navigator of the human body. It gravitationally attracts the right people, events, and things into your life path.
Willpower Center (Heart/Ego Center)
Heart, Stomach, Gallbladder, and ThymusThe engine of competition and materiality. It relates to your confidence in the material world and your desire to prove yourself.
Emotional Center (Solar Plexus Center)
Kidneys, Prostate, Nervous System (Kidneys, Nervous System)If your Emotional Center is defined, it is your absolute inner authority. Emotions are waves without logic.
Intuition Center (Spleen Center)
Spleen, Lymphatic and Immune System (Lymphatic System)The voice of intuition quietly speaks only once in the “present moment”; it does not reason with logic. It also governs the fear of time and death.
Sacral Center
Ovaries and Testicles (Reproductive Organs)An inexhaustible power center. As long as you do what you love, the Sacral will continuously generate enormous energy.
Root Center
Adrenal System (Adrenal Glands)The source of stress. Defined people come with their own pressure pump; undefined people absorb external urgency like a sponge.
Defined and Undefined: The Awakening of the Not-Self Theme in Human Design
In Human Design, **colored (defined)** energy centers represent your naturally stable, continuously operating energy field — your weapon for influencing the outside world. Meanwhile, **blank (undefined)** centers are your receptors, which not only absorb others' energy but also amplify it and return it twice over.
90% of the anxiety, internal friction, and wrong decisions in our lives stem from the **“Not-Self”** — that is, trying to find fixedness in blank centers. Understanding your energy centers is like getting the ultimate human manual for “PUA-proofing” and “anti-internal-friction”.
Human Design and Energy Center Basics
Does a blank (undefined) energy center mean I'm weak?
Not at all. A blank center is where you have the greatest potential to become a “wise one.” Because you don't have a fixed operating pattern, you can keenly sense and read the state of others. Blankness doesn't mean lack; it means infinite flexibility and a window to experience all things in the world.
Are people with all energy centers full (all centers have color) destined to have a good life?
The more defined energy centers, the more stubborn a person is and the harder it is to be changed by the outside world. Although their energy is stable and self-sufficient, they are also prone to falling into their own information cocoon. Human Design has no good or bad, only “whether you act according to your inner authority and strategy.”
