The <rLr-sfB-g> /chuff, long low weak grunt, chuff, yip, early falling weakening whine, short low weak growl/, “realm of minds, noosphere” sometimes poetically called the <jhq-sfB-g> /short falling strengthening growl, huff, etc/ or “mind sea” is an important theological concept in the Bright Way. Wayfarers view evolution, indeed the wider development of the universe as a whole, as a teleological process. A planet accretes from a stellar nebula; life arises from the inert matter of the planet's geosphere, giving rise to the biosphere; and, through the process of biological evolution, life grows more and more complex until sapience emerges, giving birth to the noosphere: the realm of rational thought, reflection, social connection, and communication.

The Light is likened to a gardener tending a flowerbed, with worlds growing from a lifeless geosphere, to a growing biosphere, and eventually flowering into a noosphere as a sapient species emerges. Claravian doctrine holds that The Light has tasked the yinrih as a species with drawing these hitherto isolated noospheres together into union, hastening the ultimate convergence of the universe to a perfect whole.
