Can awakening to planetary consciousness open pathways to personal and social healing, reconciliation and redemption in the aftermath of mass suffering like Jeju 4.3? In this article, I aim (a) to identify the characteristics of planetary consciousness using my observations on a peace pilgrimage and case examples from Jeju, and (b) to clarify how planetary consciousness is developed through transformative learning processes. Planetary consciousness is the awareness that all beings, energies and phenomena are profoundly interconnected and interdependent. The development toward planetary consciousness can be understood using models such as the Transformative Learning Process, the Radical Forgiveness Method, and the Social Healing Through Justice Model. Progressing through the stages results in openness to multidimensional thinking and knowing. Individuals and communities who have worked through transformative learning processes demonstrate the possibility of genuine healing, reconciliation and the restoration of justice and dignity.
