Within each Center there are Gates. Gates can be seen as entry and exit points that establish the flow of communication between Centers. A Gate that is activated by a Planet (colored in) describes a consistent theme or role in your life.
There are 64 Gates within the BodyGraph, corresponding to the 64 Hexagrams of the I’Ching. Each Gate has six Lines, which add further detail to the particular role of the Gate.
A Human Design Chart can have a maximum of 26 activations, which means potentially 26 activated Gates out of a total of 64 Gates. However, it is common to have more than one activation in the same Gate.Next > Planets
