The Buddha’s wisdom is knowing the right amount. It doesn’t mean knowing everything about everything, but knowing impermanence, knowing suffering, knowing selflessness. The reason we get caught up in seeing things as other than they really are is our lack of wisdom. With wisdom we know how to let go; to let go of craving, let go of clinging, let go of beliefs. We let go of the tendency to always see things in relation to a self.
What we call ‘Me’ is merely a convention; we were born without names. Then somebody gave us a name, and after being called it for a while, we start to think that a thing called ‘me and mine’ actually exists. Then we feel we have to spend our lives looking after it. The wisdom of the Buddha knows how to let go of this ‘self’ and all that pertains to it; possessions, attitudes, views, and opinions. It means letting go of the opportunity for suffering (dukkha) to arise. It means giving occasion for seeing the true nature of things. – Ven. Pasanno
