To be human is to feel, primarily. Sentio ergo sum. Feelings come and go all the time – traces of energy passing through – stimulating us to do whatever it is that we do. How we relate to a feeling depends upon us. We can ignore it – act as though we don't feel – dull and insensitive, we can resist the feeling – harden ourselves against it and attempt to deny its consequences (become a wall), we can hold onto the feeling encouraging it to develop into an emotion (become a knot), or we can simply be aware of the feeling as it happens and allow the body to respond appropriately. This last approach we call yielding.
