Yichuan YizhuanLine statement
The fifth line, possessing yang firmness and central correctness, occupies the position of honor. Its talent and virtue are completely good and completely beautiful; this is 'the well is clear; a cold spring to drink from.' 'Clear' (lie) means sweet and pure.
The spring of a well considers coolness its excellence; a cold spring that is sweet and pure can be drunk by people. In the way of The Well, this is the utmost good. Yet the text does not say 'auspicious' because The Well achieves success only when water emerges at the top.
Since it has not yet reached the top, it has not yet come into use; therefore, only upon reaching the top is it spoken of as 'supreme good fortune.'
