Hi Steve,
I wondered if these images might help?
Hand near chest, chin, (also on stomach) shows partially opened fist. Some of the images look very similar to martial arts positions Im familiar with.

Hand near chin
I wasnt able to find any images with hand around the ear area, but question: Can the cotton be wetted before being inserted? Can you elaborate more about the ear position? What steps should be taken to avoid puncturing the ear drum? What should our mind be doing during these steps? Are we seeking to empty our thoughts, or focus on something specific? What about breathing? Deep breathes or shallower, steady breathes?
Thanks!
