So what, according to Buddhism, is wisdom?

The highest wisdom is seeing that in reality ALL things are incomplete, impermanent, and not the self.

By understanding this, one can be free and secure in the state of which is called Nirvana.

However it is not ‘wisdom’ if we simply believe what we are told. True wisdom is to directly see and understand for ourselves.

This is then the path of those seeking Nirvana. To sit with the full knowledge of absolute impermanence, and removal of all attachments, as attachments drive suffering.

A lot easier said than done, am I right?
