There is a fundamental classification of conch shells occurring in nature: those that turn to the left and those which turn to the right. A right-spiraled conch is a rare find and is considered sacred in Buddhism. The right-spiraling movement of such a conch is believed to echo the celestial motion of the sun, moon, planets and stars across the heavens. Curiously, the whorls of hair on the Buddha’s head are right-directional; so are his body hair and the curl between his eyebrows. His navel too, is shaped like the right turning conch shell.
