I first learned the full primary series through David's primary series video courtesy of my teachers at the former Jagad Yoga Shala.
Although how he teaches some asanas in the video contradicts what I learned from Paul & Neil -- like straightening the legs and lifting the heels in kurmasana (although I think it helps in some way) -- watching his video again reminded me of the time when I was just starting this journey.
Hope you find inspiration in David like I did.
Happy Easter.
