1) When we become Jivan Mukt then we become the Charan Dhool of the entire creation, but given a highly respectable place in the Dargah of Akal Purakh Ji.  When we become Jivan Mukt then our word becomes the word from God.  GurBani calls a Braham Gyani as Parmeshwar – God, “Mukt Jugt Jee-a Ka Daata,”  “Puran Purakh Vidhataa,” and so on.  Therefore, the word of such souls becomes Amrit Bani.  Such souls become the source of GurParsaad for others and are blessed with the divine power with which they can instantly plant Naam in our Surat. 

2) Mool Manter gives the definition of the Mansarovar – the Amrit – the Nirgun Jyot – Dhan Dhan Paar Braham Parmeshwar.  Mansarovar is purely the collection of all of the divine qualities that form the basis of the spiritual world – Eternal Truth.  Collection of all of the divine attributes of Akal Purakh which take the name of Nirgun Saroop.  Everything has originated from the Mansarovar and the Mansarovar is the origin of everything and this is the Only Eternal Truth.  Everything else is perishable and prone to change, the Mansarovar doesn’t change.  It has been, “Aad Sach.  Jugaad Sach.  Hai Bhi Sach. Nanak Hosi Bhi Sach.”  So a soul which brings in all of the mandatory divine attributes of Akal Purakh becomes a Suhaagan and then a Sada Suhaagan and merges in the Mansarovar.  That soul always and forever remains in the Mansarovar and drinks the Mansarovar continuously.  Drinks the never ending stream of Atam Ras Amrit – the highest Amrit – Dhan Dhan Mansarovar.   Guru Sahibs have taken a drop of the Mansarovar and tried to explain the eternal super powers of the Mansarovar, the Nirgun Saroop of Dhan Dhan Paar Braham Pita Parmeshwar Ji in GurBani.  Since GurBani has come from the Mansarovar that is why it is Amrit Bani.
