I have recently been wondering about the function of wisdom in the dharma. I read a primer on it on the Dutch-language Boeddhaforum website which contained many sutra references, and while some of it was rather circular such as “wisdom helps develop the path, the essence of wisdom is right view, therefore wisdom accords with the path” there were other references which pointed to wisdom as a separate quality which helped develop the dharma.
The primer was in Dutch but I’ve gotten together a Google Translate powered English version for you, here is the link:
Perhaps some people will find it an interesting read, although it is quite long.
Wisdom is better than any wealth.
Because through wisdom you obtain the ultimate goal.
Because people commit bad deeds through ignorance
While they live on life fail to reach the goal. (MN82)
