So, get familiar with the 10 Movements of your head, and then during your asana practice, as well as during the day, pay more attention to what you are actually doing with your head and neck. Let it be the flower at the top of the stem.
You are always doing something. Start being aware of what you ARE doing. Know what your options and choices are, and then mindfully self-correct so you are always doing the one that's feeling the most groovy. God, I haven't said that word in, what, 40 years?
With Love and Pranams,
From Erich
