Whenever we refer to the Shabad Hirda we don’t mean the physical heart that pumps our blood, but the Hirda is one of the Sat Sarovars that is a part of our soul – Suksham Dehi and not the physical body.  This Sat Sarovar is located in the spine area right behind the middle of our chest.  This Sat Sarovar is illuminated with the GurParsaad of Naam Amrit – Sat Naam.  This is a source of infinite divine powers and is a place for all of the divine qualities, which are nothing but all of the divine powers.  When the Hirda becomes a Sat Hirda then it gets filled with all of these divine powers and takes us to the heights of the spiritual world.   God lives in the Hirda.  Hirda is the house of God.  Hirda is a place where God lives.  Hirda is the true Gurdwara.  But, what has been happening is that the Hirda has been suppressed and has been covered by the scum of Maya.  However, when the Hirda becomes cleansed of the scum of Maya then God appears in that Hirda.  In all practical and physical senses there comes a Puran Jyot Parkash it becomes a Puran Sachyara Hirda.  A place under the Puran Sachyari Rehat, the internal compliance of winning over Maya.
Each and every Hirda has the super divine power to become a Puran Sachyara Hirda and has the hidden ability to allow God to appear in the creaton with all His super divine powers.  That is how the Creator has created the Hirda.  He is hiding Himself.  This means the Creator is hiding Himself in every Hirda.  He is revealed by going beyond Maya.  That is a mandatory divine law, and that is how the entire creation operates – under His Puran Hukam.
