International Human Design School
These books are transcripts of The Channels Course by Ra Uru Hu that were held in Taos, New Mexico in 1999 from April 8-18.
They include over 40 hours of lectures on all the channels in a Human Design chart. Ra also gives an in-depth view of how each channel adds to the overall nature of the circuit of which it is part. He discusses at length what quality each channel demonstrates about the entire circuit.
