The nine centers of Bodygraph: defined and undefined centers. Understanding human personality through the Bodygraph system.

In the world of astrology and human psychology, there are many different approaches to understanding human personality. One such approach is the Bodygraph system, which uses nine centers to describe various aspects of the human psyche. This article will explore these centers and their influence on human personality.

Introduction to the Bodygraph System

The Bodygraph system is part of a broader concept known as Human Design. It combines elements of astrology, the I Ching, Kabbalah, and the Indian chakra system to create a unique approach to understanding human personality. The nine centers described below play a key role in this process.

The Nine Centers of Bodygraph

The nine centers of Bodygraph can be divided into two categories: defined and undefined centers. Defined centers are those where there is a specific energetic presence that influences the individual's personality. Undefined centers, on the other hand, do not have this influence but can be influenced by other centers.

Defined Centers

  • Crown Center: related to spirituality and higher mind.
  • Ajna Center: related to life experience and learning.
  • Ego Center: related to personal identity and self-esteem.
  • Sacral Center: related to creativity and life force.
  • Solar Plexus Center: related to emotions and intuition.

Undefined Centers

  • Head Center: related to thinking and logic.
  • Heart Center: related to emotions and compassion.
  • Root Center: related to daily life and habits.
  • Sacral Center (as undefined): in some cases, may be influenced by other centers.

Influence of Centers on Personality

Each center has its own unique influence on a person's personality. For example, a person with a defined Crown Center may be more spiritual and philosophical, while a person with an undefined Head Center may struggle with logical thinking.
