Whatever God does is for the good. As the doctor operates on a boil and removing the poisonous matter in it cures the ailment, likewise God gives you pain, washes and wipes you and pulls you in His lap. God rectifies all faults and says: "give me all thy impurities – and accept immortality in return". He causes pain and gives unhappiness to the devotee to intensify his eagerness and yearning. God accepts his worship through pain and tears.
