There is a field of thought that once you encounter a feeling in a body and if you stay with this feeling, it will give rise to the sensation beneath that feeling. And if you stay with that sensation, you will reach the chemical reactions that produce the sensation. Staying with the chemical reactions, you will reach the molecules that make up these reactions. With enough time, the molecules can be divided and broken down into the smallest particles of living substance within our body where they can no longer be divided.
