The Generator is one of the five types of Human Design, the system's top-level classification of people by the configuration of their bodygraph. Human Design is a modern esoteric system, originated in 1987 by Ra Uru Hu (born Alan Robert Krakower, 1948-2011), who presented its content as received teaching rather than as an inherited tradition. It is roughly four decades old and is best read as a contemporary synthesis, not as ancient wisdom or established fact. Ra Uru Hu combined four older systems that had never before been joined: the I Ching supplies the sixty-four gates, the Hindu chakra model the nine centres, the Kabbalistic Tree of Life the connecting channels, and Western astrology the method of calculation.
To each type the system assigns a strategy, a signature said to accompany living in line with it, and a not-self theme said to signal living against it. For the Generator, the strategy is "To respond to life," the signature is Satisfaction, and the not-self theme is Frustration. These are prescriptive elements of a contemporary esoteric framework dating from 1987; they are described here as the system's own model and are not offered as medical, psychological or life advice, nor as established fact.
