How can that bright and common future that all religions have depicted for humanity be realized? When will the world be freed from suffering and achieve light and peace? How can individuals contribute to the realization of that future and become influential in this process? The way we answer these questions is closely tied to our worldview and our definition of the promised future. If we interpret the future solely within the span of our earthly life, our ability to make an impact will be limited to the short period from birth to death. However, if we wish to play a significant role in the realization of the common future of the world promised in religions, we must first gain a clear understanding of the future and redefine this long-standing concept.
