Shula Vrata is one of the eight Mahavratas. It is observed on the day when the sun shines in the Makara rashi (Capricorn sign) in the month of Pushya (mid December to mid January) on new moon day. On that day the observer should pray to the Lord holding three-headed spear (Shula) accompanied by Goddess Shakti. The god is anointed with `Abhishekam` and offered `Naivedyam` (holy offerings). The donation should be given to the devotees who wear Rudraksha beads around their necks. The observer of the vrata should have only one meal along with the devotees.

One would get victory over all the enemies and free from all the diseases if they observe the Vrata. They will also get the boon of offspring and prosperities. And in conclusion the devotee will get union with Lord Shiva. By observing this Vrata, Maha Vishnu was able to kill the cruel demon Kalanemi, Parashurama killed Kartaviryarjuna. Mahavishnu also got rid of worst headache after observing this Vrata and Brahma got relieved of highly painful stomachache because of the glory of this Vrata. The great powerful lord Virabhadra explained the greatness of this Vratam to VanuKambha.
