In this work, Prabhuji guides us from the conception of a personal God, through the notion of an abstract Being, until the discovery of the Last God. Following the reflections of Martin Heidegger, we will explore the ontological depths of Being. On this journey, we will see that the divine transcends categories and concepts. By recognizing the limits of human comprehension, the humility necessary to access the presence of the sacred will arise. Open to the unknown, we will explore the paths of contemplation and meditation. Discovering the Last God is immersing oneself in the absolutely unknowable and unveiling the deepest mysteries of consciousness. Prabhuji is a writer, abstract painter, an avadhūta, a universalist Advaita mystic, faithful official member of Hinduism, the creator of the Retroprogressive Path, and a realized master. When he was eight years old, he had a mystical experience that motivated his search for the Truth, or the Ultimate Reality. This transformed his life into an authentic inner and outer pilgrimage. He has absorbed the teachings of great masters, shamans, priests, machis, shifus, roshis, shaykhs, yogis, pastors, rabbis, kabbalists, monks, gurus, philosophers, sages, and saints whom he personally visited during his years of searching. For him, awakening at the level of consciousness, or the transcendence of the egoic phenomenon, is the next step in humanity's evolution. Prabhuji chose to retire from society and lead the life of a hermit. His days are spent in solitude, praying, writing, painting, and meditating in silence and contemplation.
