Aloha energygirl2013,
Do what is best for you.
Chunyi mentions that these are a good opportunity to release blockages if you can continue, calling on your master's or universe's energy to assist you, relax, take a breath and let your shoulders sink, and bring your focus back to your breath and the visualization. It's not a lot of fun to be in the middle of it and to here Chunyi say "Oh, what a great opportunity to heal!"
Much Love,
Shawn
