Wisdom and knowledge are two entirely different matters. Knowledge is very finite. The collection of objective knowledge is like a drop in the bucket compared to what it is to be wise.
Being wise is when you get out of the time-space locus that says, ‘I am me who knows.’ And then you merge with that which is around you. You become wisdom.
When you become wisdom, you don’t know you know. You gave that one up. But you are wise. Then whatever response comes out of you is the optimum response. At the same time nothing is happening inside you at all.
