Tao of Lao Tzu - 27.

'' Do not imagine that an integral being has the ambition of enlightening the unaware or raising worldly people to the divine realm. To him, there is no self and other, and hence no one to be raised; no heaven and hell, and hence no destination. Therefore his only concern is his own sincerity. ''

• Lao Tzu - 'Hua Hu Ching' - verse 27.
