Breathing is very important in Level 1. Without it you will die.
Breathing technique is not vital--it becomes vital in Level 2, however. It is more important that you slow your breathing so that you are breathing 3-5 cycles per minute, less if you can. Deep breathing is very good.
Visualization is vital and so is being able to feel the energy. You do not want to focus on a problem, but focus on the energy flowing through your body, focus on blockages turing to air and going to the ends of the universe.
