Ever since you let out your first cry, you've been breathing.
Sometimes shallow, most of the time calm and steady.
Conscious breathing — breathing while paying attention to the breath — can be your anchor. It's one thing that will always be with you.
Breathing is both automatic and under your control. When you slow down and deepen your breath, your whole body responds by calming down. Your mind does too.
The breath is the most powerful tool you have to determine your experience.
