Thanissaro Bhikkhu

You've strayed from the middle path.

Or you may see yourself as something you wouldn't care to be, a pig or a dog, a bird or a rat, crippled or deformed,

If you let yourself get upset, that's indulgence in self-affliction.

Some people really let themselves get carried away

As soon as they start seeing things, they begin to think that they're special, somehow better than other people.

They let themselves become proud and conceited, and the right path has disappeared without their even knowing it.

If you're not careful,

This is where mundane knowledge can lead you.

But if you keep one principle firmly in mind, you can stay on the right path.

Whatever appears good or bad, true or false,

Don't let yourself feel pleased.

Don't let yourself get upset.

Keep the mind balanced and neutral and discernment will arise.

you'll see that the visions or signs display the truth of stress.

They arise, they are born, they fade or age, and they disappear or die.

If you get hooked on these or your intuitions, you're asking for trouble.

Knowledge that proves false can hurt you.

But knowledge that proves true can really hurt you.

If what you know is true and you go telling other people, you're bragging.

If it turns out to be false, it can backfire on you.
