As we get closer to pleasure, the closer we get to vulnerability.
For pleasure is possible when a person connects with himself, stops analyzing, and simply goes through what's happening to him.
The closer we are to vulnerability, and so, to real feeling, the less control we have. And the lower the control, the closer to the surface everything that is contained. That's why people who hold back pain, anger, grief, or fears are almost inaccessible to pleasure.
Pleasure and vulnerability are inseparable. You cannot turn on all the senses and turn off what is not lived. And as soon as control is reduced, the restrained and hidden comes to the surface with all clarity.
