Thanissaro Bhikkhu

You have to use a fine weave to filter down to the deeper levels and penetrate into the deeper levels by contemplating over and over again through level after level.

This is why there are many levels to being mindful and discerning.

Filtering on into the details.

And this is why examining and becoming fully aware of your own inner character is so important.

The practice of meditation is nothing but catching sight of self-deceptions, to see how they infiltrate into the deepest levels and to see how even the most blatant levels fool us right before our very eyes.

If you can't catch sight of the deceits and deceptions of the self,

your practice won't lead to release from suffering.

It will simply keep you deluded into thinking that everything is you and yours.

To practice in line with the Buddha's teachings is to go against the flow.

Every living being

deep down inside, wants pleasure on the physical level and then on the higher and more subtle levels of feeling, such as the types of concentration which are stuck on feelings of peace and respite.

This is why you have to investigate into feeling

so that you can let go of it and thus snuff out craving through being fully aware of feeling as it actually is, free of any self, in line with its nature, unentangled, uninvolved,

This is what snuffs out the virus of craving so that ultimately it vanishes without a trace.
