Last week, I stood at the entrance of what scholars believe could have been the inspiration for Plato's famous allegory—a cave nestled in the ancient hills outside Athens. As sunlight filtered through craggy stone, casting dancing patterns at my feet, I felt the weight of 2,400 years of human wisdom pressing upon me.

In my third reflection from Spain's Diagrama centres, I witness a profound reimagining of what it means to work with troubled youth.

This scene, repeated countless times across Diagrama's centres, illuminates what might be the most revolutionary aspect of their approach: the primacy of relationship in the work of transformation.
