According to GurBani, only the ones who reach the Puran Awastha in the Puran Bandgi stage and are blessed by Dhan Dhan Paar Braham Pita Parmeshwar Ji to preach to the Sangat are authorized to preach and not anybody else.  The ones who become preachers without reaching the Puran Awastha are Dargahi criminals and don’t do any good to anybody, but put the innocent Sangat in these kinds of illusions by their false preaching practices.
