'DU'A KARAW-WI' is an act by which we beg for forgiveness of our sins. We stand before Mukhisaheb or Kamadiasaheb, Mukhiyanima or Kamadiyanima with joined hands and say:
  "TOBO TOBO TAKSIRDAR, BANDO SAR TA PA GUNEHGAR, GAT BAKSHE SHAH PIR  BAKSH�".
which means,
  "I REPENT, I REPENT, I AM A SINFUL PERSON; SINFUL FROM HEAD TO FOOT. IF THE  JAMAT FORGIVES, SHAH PIR (HAZAR IMAM) FORGIVES".

Mukhisaheb/Kamadiasaheb, Mukhiyanima/Kamadiyanima accepts the Du'a and says:  "ALIYYULLAH NIYYAT MURAD KABUL KAR�, KHANAVADAN".

which means:

  MAY MOWLA ALI (HAZAR IMAM) ACCEPT YOUR GOOD INTENTIONS AND WISHES and MAY YOU AND YOUR FAMILY PROSPER".

We must perform this act every morning and every evening. We must perform it very sincerely and be careful not to commit any sins again.
We commit sins when we disobey Hazar Imam.
We must keep away from all sins and try our best to become better every day.
Hazrat Imam Sultan Muhammad Shah says in his Farman:

"YOUR EYES, TONGUE, HANDS AND EVERYTHING SHOULD BE PIOUS (BE FULL OF GOODNESS) AND NOTHING SHOULD REMAIN BUT PIETY (GOODNESS). A PERSON HAVING THESE QUALITIES IS AN ANGEL".

We must therefore think good, speak good and do everything that is good and become angels. This will make our beloved Hazar Imam very happy.
