"Things that are formless are called the 'Tao'; things that have form are called 'vessels'..."
When Zhao Douan recited this sentence, the old Heavenly Master's narrow eyes slowly narrowed, carefully savoring the meaning behind the words.
So-called "formlessness," Zhao Douan had not understood for a considerable time during his previous life studies.
It sounded obscure, and it was only after starting to work that he gradually understood: it simply referred to
the contrast between formless things and tangible things.
The most commonly mentioned "formless," referring to the objective laws of things, such as the rise and fall of dynasties, exist objectively yet cannot be touched or seen.
Distinct from tangible and utilitarian objects.
Zhao Douan cited "The Book of Changes" to equate cultivation with pursuing the "elusive formlessness."
Cultivation involved practicing Magic, mastering extraordinary powers, which was akin to pursuing the tangible "vessel."
