- Maasi month (Feb-Mar)
- Magam (Magha) star
- Holy bath at sea and tanks
- Mahamaham every 12 years
Where it began
Maasi Magam takes its name from the month and the star. It is believed that a bath on this day washes away wrongs and brings blessings.
Legend says the holy rivers came to Shiva asking how to be cleansed of the sins left by people who bathed in them. He told them to bathe in the Mahamaham tank at Kumbakonam, so on this day all rivers are believed to meet there.
Another story tells that Lord Murugan taught the meaning of Om to his father Shiva on this day.
