Thanissaro Bhikkhu

This is why those who truly know see that knowledge is the essence of stress.

It can hurt you.

Knowledge is part of the flood of views and opinions over which we have to cross.

If you know, simply know and let it go at that.

You don't have to be excited or pleased.

People who've studied abroad when they come back to the rice fields don't tell what they've learned to the folks at home.

They talk about ordinary things in an ordinary way.

The reason they don't talk about the things they've studied is because, firstly, no one would understand them.

And secondly, it wouldn't serve any purpose.

Even with people who would understand them,

No matter how much you know, you have to act as if you know nothing.

Because this is the way people with good manners normally act.

If you go bragging to other people, it's bad enough.

If they don't believe you, it can get even worse.

So whatever you know, simply be aware of it and let it go.

When you can do this, your mind can attain the transcendent, free from attachment.

everything in the world has its truth.

Even things that aren't true are true.

That is, their truth is that they're false.

This is why we have to let go of both what's true and what's false.
