Module 1 should have you understanding, in theory AND practice, the first steps and GAVY Puzzle Pieces of the system. As this outlined and taught in your book, Ashtanga Yoga Made Simple.
In Module 2, we add on the next couple GAVY Puzzle Pieces, so this simple practice begins to grow, slowly, slowly. Any time it starts to feel like too much, too fast, … just take a step back, slow down, review, and allow the mind to catch up.
Both in doing the practice and teaching the practice, less is more, and “Repetition is the Mother of Perfection!” As you are doing the practice and the teaching exercises, either share the teachings with a friend, OR, set up your camera in front of you and record yourself. This way you can critique yourself in positions, words, and showing skills.
