It is said that Shiva opens his third eye to burn Desire (Kāma) to ashes. However, this third eye also stands for enlighten and knowledge. That is the reason Indians apply Tilak on their forehead between their eyes, as a symbol of that realization. The statue of Shiva features the River Ganga (the Ganges) in his jatas (matted hair), who flows from his head making him immortal, along with a crescent moon indicating a perfectly controlled mind. The idol also has a serpent twined around his that stands for wisdom and eternity.
