In Hindu mythology, Parvati, wife of Shiva, once closed the eyes of her husband playfully in a flower garden at their abode atop Mount Kailash. Although only a moment for the gods, all light was taken from the universe, and the earth, in turn, was submerged in darkness for years. Parvati performed penance along with other devotees of Shiva. Then her husband appeared as a column of fire at the top of Annamalai hills, returning light to the world. He then merged with Parvati to form Ardhanarishvara, the half-female, half-male form of Shiva. The Arunachala, or red mountain, lies behind the Arunachalesvara temple, and is associated with the temple of its namesake. The hill is sacred and considered a lingam, or iconic representation of Shiva, in itself.
