Breathing is far more important than we realize. Its benefits on the physical and mental planes are innumerable; relaxing the mind, regulating hormones, mental clarity, and greater awareness. But it is the spiritual purpose of the breath that is most significant.
Some of the most deeply hurt people try very hard to cover up their true feelings. They are masters at hiding their emotions from the world, so as not to show a perceived weakness, they've been conditioning themselves to believe they can never succumb to. And so in silence, they suffer as they hold your hand through your latest work-related drama, dry your tears over your latest break-up, and celebrate with you during your latest victory.
