Arumugan is one among the numerous names of Muruga. He is known as Arumuga, or the one with six faces, because when Goddess Parvati joined him he had six faces and twelve hands.
Lord Muruga, also known as Skanda, Subrahamaniya and Kartik, was born as six different babies to Lord Shiva after he awoke from the deep meditation after Goddess Sati’s death. Six Krittika stars looked after the six babies.
When Goddess Parvati found the six babies, she hugged them, and they became one. He then came to be known as Arumugan.
