ever since I learned about them; Quantum Physics tells us that everything is made up of energy; we are constantly vibrating. Therefore, using sound tones and vibrational healing actually makes sense to me on a Scientific level. I haven't seen much research about, but this audiobook helps me relax, and I can feel the music in my body. Is it healing me? Who knows?! But I sure do enjoy it :)
Glenn Harrold has a nice voice, and his vocal techniques really resonate with me in a positive way. I listen to this almost every night.
