From the Star Trek Encyclopedia (4th ed., vol. 1, p. 109), the literal meaning of Buddha was "the enlightened one". Buddha was "an ancient Earthphilosopher, circa 5th century BCE, whose teachings form the basis of the nontheistic religion of Buddhism. In Earth folklore, it is considered good luck to rub the abdominal region of icon representations of a statue called the "Laughing Buddha". Although the icon actually represents an ancient Chinesedeity, rubbing the belly of the Buddha is regarded as a gesture of respect of both religious figures."
