Third Eye

A peculiar ninjutsu of Gaara's. With chakra, he connects a sand-made eye to his optic nerve, which enables him to know what happens in the sand eye's field of vision. This is genuinely a third eye for its user. Gaara can control the size of the eye depending on its use. Its main purpose is spying, since it can form and disperse in any location on command. He also uses it while within his Sphere of Sand so he can see what's happening outside of the protective dome.

Trivia

 * In Buddhism and Hinduism, the third eye is considered to be the eye of knowledge and symbolises enlightenment.
