Chapter 1, Part 3 - Lieh Tzu

The Master Lieh Tzu said: 'The virtue of Heaven and Earth, the powers of the Sage, and the uses of the myriad things in Creation, are not perfect in every direction. It is Heaven's function to produce life and to spread a canopy over it. It is Earth's function to form material bodies and to support them. It is the Sage's function to teach others and to influence them for good. It is the function of created things to conform to their proper nature.

'That being so, there are things in which Earth may excel, though they lie outside the scope of Heaven; matters in which the Sage has no concern, though they afford free play to others. For it is clear that that which imparts and broods over life cannot form and support material bodies; that which forms and supports material bodies cannot teach and influence for good; one who teaches and influences for good cannot run counter to natural instincts; that which is fixed in suitable environment does not travel outside its own sphere.

'Therefore the Way of Heaven and Earth will be either of the Yin or of the Yang; the teaching of the Sage will be either of altruism or of righteousness; the quality of created objects will be either soft or hard. All these conform to their proper nature and cannot depart from the province assigned to them.'
