The dust of the Sant’s feet – Charan Dhool is the most pious thing one can achieve, there is Jivan Mukti hidden in this Charan Dhool, there is infinite divine super power hidden in the Charan Dhool of a Puran Sant Puran Brahamgiani.  The GurBani Guru also tells us to take the Charan Dhool of a Puran Sant Puran Brahamgiani and take a bath with that.  As said earlier Mahima of this Charan Dhool is beyond description, we can only do this and enjoy the benefit otherwise we will never be able to see what happens when we do so.  This is true for every Shabad of GurBani Guru, unless we do it we will never be able to realize the benefit and reward, and those who do so become Dhan-Dhan.
