Are nada-sounds like a tuning fork to raise your vibrational state?
I have been made aware some time ago that this soft, hypnotizing, enveloping sound I "hear" permanently in my head is a nada-sound. I did a quick search about it and read about these sounds progressing from lower to higher pitches along with spiritual growth. I also got distracted with feelings of energy associated to it ("Mickeymouse Ears") or not (in- / through-flowing energy), and it was suggested to me to focus on the nada-sound only which I have been doing for about a week now.
At first, it was just the sound. Progressively it became more than just the sound. I feel like my energy levels, my vibrational state, raises and tunes to the frequency of the sound.
Can that be? Can the nada-sound be sort of a tuning fork to get us to raise vibrational states? A bit of the Universe coaching us along the awakening path?
