After you have done your bowl ceremony, sit quietly for a moment. Start a metronome or keep count in your head and start your breathing exercise.
For the breathing exercise:
breathe in slowly for a count of 7
hold for a count of 7
breathe out slowly for a count of 7
Continue the breathing exercise for 15 minutes.
As you breathe, silence your thoughts. Clear your mind of all images. If there are other members of your family, you should do the breathing together. Synchronize your breaths so that you are all breathing as one.
