Where does the Human Design come from?
For information about the origin of the Human Design System, read this article.
Can my design change?
No, you design is determined by your time & place of birth and this never changes. Your design remains the same for your whole life.
The energy is neutral, but the way it gets expressed can be positive or negative. That which can heal can also kill. One can be busy working all the time, and do what brings him satisfaction and fulfillment, or running around like a mad man always doing something, initiating and instead of satisfaction only frustration and anger.
So although your design never changes, the way it gets expressed, the way you experience it, the frequency of your aura, changes. And it’s all about how you make your decisions.
Can I do something to fix my open centers?
The open or undefined centers (the white ones) are places where we go to school in life. They are not empty, broken or bad. They are so open to outside conditioning that they become the source of our Not-self behavior, taking us away from who we are. Thus we think the open centers are somehow 'bad' and needs fixing. But when you live according to your design, it is through your open centers that you get your deepest wisdom.
How come there are only 4 types of people? It seems too simplistic.
The type really is about the specific characteristic of its aura and specific strategy for decision making. Each type has a different strategy for optimal movement in life. There are countless variations within each type. There are many aspects in each chart and each person has a highly unique definition. That goes much deeper then just the defined centers, gates or even the lines. What you see in a bodygraph is really only a surface. So although there are only 4 types, there are almost endless combinations of definition.
Can the Human Design help me to have better relationships?
Yes. Following your strategy and authority will help you to make the right decisions. Be it entering into relationship with the right partner, or being who you are when in a relationship and not falling for the Not-self strategies of your open centers. Your relationships will be more and more harmonious. It can also mean that if you are with a partner that isn't right for you, the relationship will naturally come to an end. Also knowing your partner's design is so very helpful in understanding each other and honoring each other's individuality. The composit or partnership readings are a great help in this.
