We suggest you turn to the Tao Teh Ching:
21 The omnipresent Virtue will take shape According only to the Way. The Way itself is like some thing Seen in a dream, elusive, evading one. In it are images, elusive, evading one. In it are things like shadows in twilight. In it are essences, subtle but real, Embedded in truth. From of old until now, Under names without end, The First, the Beginning is seen. How do I know the beginning of all, What its nature may be? By these! -- tr. R. Blakney
