Carmen Iglesias

Carmen taught vinyasa for years before her body asked for the slow room. She now teaches yoga nidra and writes about frequencies, rest practices, and the solfeggio tradition — with respect for the ritual and honesty about the evidence. Her entries on 528 Hz explain what the tone is, where the lore comes from, and what listening actually does. Teaching rest professionally since 2016 gave her a rare vantage point: she has watched hundreds of nervous systems settle, and she knows how much of that settling comes from the tone and how much from the permission to lie down and be led. Her writing keeps those honest proportions. On solfeggio, she does the genealogy properly — the medieval hymn, the numerological reading added centuries later, the modern claims stacked on both — because she believes a ritual is stronger, not weaker, when you know its actual history. On practice, she is specific: how to use a single tone as an anchor for attention, why a fixed frequency suits the nidra state better than shifting music, what a listener should notice in the first ten minutes. She holds a simple line that runs through everything she writes: the frequency is not magic, the rest is not optional, and a practice kept gently for months outperforms any tone chosen perfectly once.

Writes about: deep rest, solfeggio frequencies, sound ritual.
