As most of you know, being Quad Right is a variable (PRR DRR). There is also a Quad Left (PLL DLL). Here are a few YouTube videos that cover a beginning to intermediate introduction to variables in human design.
Ra Uru Hu (Founder of Human Design) on variables.
Here is where you can get your human design chart, which Ra mentions at Jovian Archives. There is also a free media library.
The following video is a more in-depth view of the variables from certified Analyst Laveena Archers.
Laveena is a great teacher. Some of her topics are more for people who have gone through 5-7 years of deconditioning or want to be an analyst like her. However, she also teaches some beginning topics. Visit her main homepage to read her blog and learn more about her classes. I also recommend joining her free community.
