Thanissaro Bhikkhu

Desires for this and that will seep in and influence the mind so that it gets carried away with inner and outer feelings.

Quiet in a way which doesn't let the mind become attached to the flavors of feelings.

The desire for pleasure is like a virus deep in our character.

What we're doing here is to make the mind stop taking pleasant feelings into itself and stop pushing painful feelings away.

It's because we're addicted to taking in pleasant feelings that we dislike painful feelings and push them away.

So don't let the mind love pleasure

and resist pain.

Let it be undisturbed by both.

If the mind can let go of feelings so that it's above pleasure, pain and indifference,

That means it's not stuck on feeling.

And then try to observe.

This is something you have to work at mastering in order to release your grasp on feelings once and for all, so that you won't latch onto physical pain or mental distress as being you or yours.

If you don't release your grasp on feeling, you will stay attached to it, both in its physical and in its mental forms.

If there's the pleasure of physical ease, you'll be attached to it.

As for the purely mental feeling of pleasure, that will be something you'll really want, you'll really love.

And then you'll be attached to the mental perceptions and labels which accompany that pleasure.

The thought formations and even the consciousness which accompanies that pleasure.

You'll latch onto all of these things as you or yours.

So analyze physical and mental pleasure.

Take them apart to contemplate how to let them go.
