This "way" is wonderfully described in the I Ching (Book of Changes), where from we have excerpted a short commentary of
Richard Wilhelm on the Hexagram 19 - Lin / Approach:
The water endlessly flows and fills, up to a certain limit, the corners it is flowing through; the water is not "afraid" of any
dangerous place, of any "falling" and there is nothing making it lose its essence. Under all circumstances, it remains equal to its nature.
Being attentive to the characteristics of water, the Taoist disciple has created a similar model of human behavior which may be formulated as follows:
Under all circumstances one should behave like the water, one should adjust to the requirements of the moment, keeping safe his/her unchangeable essence in the meantime (here "essence"
points to his/her inner self, or true nature).
The water sumbolism was cherished by Lao Tzu in his Tao Te Ching when he said:
The highest excellence is like (that of) water. The excellence of water appears in its benefiting all things, and in its occupying, without striving (to the contrary), the low place which all men
dislike. Hence (its way) is near to (that of) the Tao. (Chaper 8:1, James Legge).
Here water offers an ethical example: to be low rather than hight while benefiting all around.
I started by quoting from the I Ching because it is the true guide for
the Taoists adepts. It shows the way one may follow, or more precisely the way one may behave in order to avoid dangerous pits.
This Book (considered to be a classic, such as The Bible) works just
fine together with the Taoist wisdom tradition.
