This series of video lectures by Ra Uru Hu introduces you to the 9 Centers of the Human Design BodyGraph and the energetic Streams that flow through them. Each Stream is a grouping of Channels within a specific circuitry, showing how energy moves in patterns that shape the way we think, feel, survive, and express ourselves. Ra explores these Streams—mental, emotional, instinctual, and more—within all nine Centers, helping you understand the purpose each one serves in daily life.

As you explore the unique function of each Center and Stream, you’ll start to see how your own energy works—where you feel pressure, where you seek truth, and how you process emotion or instinct. You’ll learn why some parts of life feel consistent while others feel open or uncertain, and how to navigate those differences. This is a great starting point for anyone wanting to better understand themselves and others through Human Design, with clear, down-to-earth explanations from the founder of the system himself.
