Also, this virtham was observed by Naradar Rishi as per the advice from Lord Ganesha for 12 months. Finally, at the 12th month, he gained his ambition and became the supreme power among the Sapta Rishis.
The story behind this viratham:
The six Karthika stars appeared in the form of Six damsels and took care of the babies to grow. When Lord Parvati came to the River Saravana where the six children were growing, she embraced all six together. And the six children turned into one boy with six heads.
As the Karthika stars played a vital role in bringing up the baby and were given immortal fame. Lord Muruga defeated the demons thoroughly and removes the miseries of all.
