Shiva Purana says: “He who worships Shiva during the holy Period of Pradosha, With the offering of lotus flowers and a total surrender, Will be blessed with longevity, devout wife, loving children and friends, And will enjoy lots of prosperity and fortune in this world”.Every month in the evening of trayodasi -13th moon phase between 4.30 p.m to 6p.m is Pradosham. It is observed in the twilight period – one and half hours before sunset and one hour after sunset. It falls twice in a month,once in the waxing period or Shukla paksha and once in the waning period or Krishna paksha. Pradosham hours are holy hours to wash away the sins of innumerable lifetimes. When one prays to the Lord with wholehearted devotion, the Lord wipes away the sins and fulfills all desires.
