The breath is so important.  Breathing, really breathing  in from the top of your head to your tailbone and even to the bottoms of your feet.  Breathing oxygen into your system keeps it alive.  Breathing out moves the co2 from the body.  In between the process of breathing in and breathing out, many things happen. 

It is important to breath in of course and equally important to breathe out.  Don’t hold your breath.  Deep breathing, whole system sustained breathing, carries a wealth of benefits.

Breathing is important in meditation.  Breathe in love. Breathe out hate.  Breathe in peace. Breathe out chaos.  Breathe in energy.  Breathe out tension.  What if however, this process is hindered?  

When I work on the breath of my clients, I help the tissues in their ribs, diaphragm and back  expand.  ‘Opening the breath’ means opening the thoracic area to enable the mechanism of breathing to occur.  It is difficult to breathe deeply if your body isn’t capable of expanding in order to do so.  Once this expansion occurs, breathing becomes easier and depth of breath occurs.  Breathing down into your sacrum resets your system.  You are able to and are allowing your body to breathe.  Taking breath in so the oxygen and co2 can work together before breathing out.
