The Thirty-Six Channels

The thirty-six channels of the Human Design bodygraph each join two of the nine centres and are formed by a pair of gates, one at each end. A channel is "defined" when both of its gates are activated by the planetary calculation, and defining a channel in turn defines the two centres it connects, so the channels are what build up the pattern of definition in a chart.

Each channel carries a theme, a "circuitry" and a keynote describing the kind of energy it represents, and the set of thirty-six is a fixed feature of the system, mapping every possible connection between the centres.
