The spiritual world of a Volk is not its cultural superstructure, just as little as it is its arsenal of useful knowledge [Kenntnisse] and values; rather, it is the power that comes from preserving at the most profound level the forces that are rooted in the soil and blood of a Volk, the power to arouse most inwardly and to shake most extensively the Volk's existence.
