Who keeps Ek-Bhukt Vrat for one day, eats food made of only one type of grain (wheat, or barley, rice etc) and donates sesame seed cow and bull next day, he goes to Shiv Lok. This is called "Rudra Vrat" and destroys all sins and sorrows.
Who does not eat any fruit in four months, from Aashaadh to Aashwin, and after that gives jaggery and one pitcher, and some gold on Kaartik Poornimaa, he goes to Rudra Lok. This is called "Shiv Vrat".
