This book investigates the lived experience of CEOs in their quest for wholeness and presents a model of spiritual intelligence for contemporary leadership. The experience of ethical and spiritual crisis in the post-modern society especially in organizational leadership, calls for deeper quest and spiritual intelligence. Four essential themes emerged from the analysis of the in-depth interviews with top leaders of different organizations across the globe: (1) Sensing Crisis, (2) Embracing Crisis (3) Awakening Hidden Wholeness, (4) and Serving Greater Good. From the analysis of the themes, a model of spiritual intelligence and leadership wholeness is constructed. This Spiritual Intelligence Model portrays the intra-dynamics of leaders’ ongoing quest for wholeness penetrating through their existential, learning, spiritual, and moral dimensions of being and the five ethical dimensions of wholeness permeating through the personal, organizational, social, global, and environmental spheres of life. This book gives a fresh perspective on spiritual intelligence and leadership practice today.
