This is the second in a series of six solfeggio meditations. Each is related to a chakra, element, color and has purported healing benefits. For some reason, audible does not seem to have the one I'd found to be the best of the series (528 Hz - Solar Plexus - fire - yellow), though all are well worth the purchase price. Sacral chakra, water, orange and facilitating positive change are the aspects that are associated with this meditation recording.
Two guided meditations are present in this audio book, the first with a wake ending, the second with a sleep ending. The listener is guided across a meadow to a river (water element) where a boat awaits to take you down the river. Background sounds, music and a calming guided meditation are signature techniques in this series, as well as affirmations. Solfeggio sounds are supposed to be rooted in an ancient scale partly derived from, and used in, Gregorian chant, originating in the 8th Century, when Paulus Dioconus wrote the hymn “Ut queant laxis” in honor of John the Baptist.
All of the meditations in this series are wonderfully calming, well presented, seem to produce results and have some efficacy for their intended healing. Though I can't be certain the solfeggio scale has added to the effectiveness, meditation has been known to have benefits spiritually and science has validated there are physiological changes resulting from meditation (as seen on a brain MRI). Sound has also been shown to have physiological effects in some studies (on the genes of flowers). In any event, I have certainly noticed beneficial changes in my perceptions and spiritual/mental state from using this (and other) guided meditations, but I find this series to be top quality and regular "go to" listens.
I have several of Glenn Harrold's hypnotherapy/meditation audio books, for me, this was the most powerful I've heard. His style took a bit of getting used to at first (this is my 4th one), but glad I stayed with it. I can't deny the results from this particular one, deep physical and spiritual shifts.
