Integrating Afterlife Beliefs of Christianity, Hinduism, Buddhism, and Shintoism Through the Cyclic Universe Model: A Multidisciplinary Approach with Practical Implications for Mental Health and Caregiving Professions

This manuscript explores the intersections of belief systems regarding the afterlife within Christianity, Hinduism, Buddhism, and Shintoism, analyzing their compatibility through the lens of cosmological theories, particularly the cyclic universe model. By addressing historical and contemporary perspectives on the nature of belief, it examines religious tenets and spiritual values from an existential, moral, and cosmological standpoint. Drawing from Spinoza’s philosophy and the concept of a cyclic universe, the authors propose a conceptual reconciliation of religious doctrines, suggesting that different religions emphasize distinct phases of an eternal cosmic cycle. The article further evaluates practical implications, highlighting how familiarity with these reconciled beliefs can alleviate existential anxieties, enhance community cohesion, and foster personal growth. This work is particularly relevant for professionals in end-of-life care, as it provides insights into integrating diverse spiritual beliefs to support well-being.
