Aloha Heartbeat,
Chunyi does set up the level I & II classes as back to back intensives. One can take level I on Friday and level II that Saturday/Sunday. They work hand in hand -as you do the level I exercises and meditations for personal healing, you can be working on others with the level II work. Chunyi says doing good things for others helps you heal. It's not a thing where you have to be in great physical condition to help others heal as you find some modalities putting out there.
Level III and four are different. There is a recommended 3 months+ amount of time of working with the level II work before taking III, and the same for level IV. There is a level of faith, confidence, and focus with the level II work that is needed to take advantage of the following two levels.
Much Love, Shawn
