I have always loved this quote by Victor Frankl because it's as applicable in therapy as otherwise, even if we do not realize, at first:
"Between stimulus and response there is a space. In that space is our power to choose our response. In our response lies our growth and our freedom."
This quote came to my mind recently during a supervision session, while discussing my clients who are experiencing trauma. In therapy, we try to understand the new emotions that are coming up, which can help in the process of healing. The key learning is that the wound doesn't just go away, but what is important is that we make an attempt to create a space of distress tolerance near the wound. And if that's done well, that is where growth will lie.
