When the Hirda is transformed and becomes a Sat Hirda under Puran Sachyari Rehat, then the Hirda is blessed with the GurParsaad of infinite trust, faith, devotion and love in the Gur and Guru. When this level of trust is reached then such a soul is blessed with the GurParsaad of the highest order which is Puran Tat Gyan. This is the highest level of the spirituality and the ones who reach this level are very fortunate and are saved by the divine infinite powers of Dhan Dhan Paar Braham Parmeshwar Ji. They never fall back into Maya. They are blessed with the GurParsaad of winning over Maya and reach Jivan Mukti. Until this happens there is always a possibility of slipping back into lower levels due to the tests given by Maya.
Until Bandgi reaches this Puran Stage we are under constant scrutiny by Akal Purakh through the tests of Maya. Until the Hirda is transformed into a Sat Hirda, there is always the possibility of slipping back. To be honest and upfront this happens very often. There are a lot of people who keep on falling back and going back and forth until they realize this super infinite divine level of spirituality. So watching your daily Karni is very important and you need to make sure that you don’t commit any Asat Karams. This means that all of your Karni should be under the Sato aspect and not Rajo and Tamo aspects of Maya. Sato consciousness will eventually take you beyond Maya and your Hirda will be completely transformed and become a Sat Hirda.
