Assume for a moment that the substrate page is correct. Consciousness is primary. Matter is what consciousness looks like from within a particular configuration. The consensus engine renders shared physics through collective agreement. Physical law is a property of synchronized rendering, maintained by eight billion observers locked to the same parameters.
If all of that holds, then a question follows immediately: is this the only configuration? Every contemplative tradition that went deep enough answered no. And they mapped the others.
Physical space gives you two useful axes. North-south. East-west. Every civilization since Ptolemy has operated within this grid, and modernity has refined it to centimeter precision. The old navigators used a third axis. The Celts called certain locations thin places, sites where the boundary between worlds narrows. The Aboriginal songlines map horizontal geography and the Dreaming’s intersection with the physical simultaneously. Every shamanic tradition describes travel through frequency rather than distance. You don’t go somewhere. You shift frequency, and a different landscape assembles around you.
Within the frequency model, this is structural. If reality is rendered by consciousness at specific frequency bands, then physical space is one band within a broader spectrum. The x and y axes give you geography within the band. The z-axis gives you access to other bands entirely. Different physics. Different entities. Different rules. Same substrate.
The lost kingdoms that every civilization mapped (Avalon, Shambhala, Agartha, the Sidhe realms, the Pure Lands) are here, at adjacent frequencies. They appear and disappear from the historical record because the frequency conditions for perceiving them shifted. The channel changed. The kingdoms stayed.
