"With breathing proceed as follows: The breath should be held and it will be gathered. If it is gathered, it becomes magic. If it becomes magic, it descends. If it descends, it quiets down. If it quiets down, it solidifies. If it is solidified, then it germinates. If it germinates, it grows. If it grows, it is attracted upward. If it is attracted upward, it reaches toward the heaven. In heaven, it ascends upward still. At the lower end, it descends still. Those who follow this will live, those who act contrary will die."
