This whole concept of Dukhbhanjani Sahib is not at all as per Sikhi or Sri Guru Granth Sahib Ji. This collection was compiled by various Babas and Deradars from Sri Guru Granth Sahib Ji in colision with some greedy publishers, just to make a fool of the innocent Sikhs who were coming to all these Baba jees for their 'Dukhs' or problems. Any shabad which had just a minor reference to any particular problem , were put in this collection. Then they were advised to do so much so number of paths of this shabad from this collection or the whole lot even and miracles will happen and your problem is going to be over or solved.

It has been clearly established from our various discussions on this forum that parroting of any particular word or Bani or Shabad is not going to give us the desired results.. But, we can minimise our sorrows or problems only by following the dictates of our Gurus in true letter and spirit, as described in Sri Guru Granth Sahib Ji.
