Thiruvathira is essentially women's festival.
Ladies on this day worship Lord Shiva and pray for conjugal harmony
and marital bliss. The other very interesting facet of the festival
is the enchanting Thiruvathirakkali dance performed by women
on this day.
Thiruvathira is being celebrated for ages now but there is no clear theory about the origin of the festival. Festival is said to be celebrated to commemorate the death of Kaamadeva, the God of love according to Hindu mythology. Some people also consider it auspicious to worship Lord Shiva on this day and take his darshan in a local Shiva temple before the sunrise. Some believe that Thiruvathira is the birth day of Lord Shiva. It may be noted that the Ardra Darshan festival of Tamil Nadu corresponds to Thiruvathira festival of Kerala.
