There are infinite expressions awakening with our true Selves (which never left us to begin with!)… Numerous “healers” (<degreed or not, doesn’t matter!) will tell you that it is a "difficult" journey (<usually to further continuance of having you as their client~!)… The truth, this passage can be as; difficult, or easy, as you choose it to be! The only reason “difficulty” exists, is because other options and possibilities haven’t been discovered and/or revealed yet… "Ask and it will be given"... Confusion is an opening for insights and possibilities, allowing inspiration (in-spirit-at-I-on) to provide answers with your journey of discovery!
The video (below) by Anon Estonia (thank you for your post!) discusses chaotic and healing frequencies (or tones)… Their first example is related to music… Later, the video shows how differing tones also create visual patterns in matter (which can be healing too!), thus showing how these tones can affect anything in their range... Enjoy the exploration!
