Cindy Wigglesworth presents spiritual intelligence (SQ) as a vital developmental line alongside physical, cognitive, and emotional intelligence, defining it as the ability to act with wisdom and compassion while maintaining inner and outer peace. Drawing on research, practical frameworks, and her SQ21 model of 21 skills, she shows how cultivating SQ transforms spirituality from abstract potential into concrete behaviors that foster wise leadership, compassionate presence, and greater collective resilience in the face of global crises.
