This 300 years old Antique Singing Bowl Sings 666Hz and its octaves, Rarest (Litté Bowl Bird Feeder)

I have this bowl for almost 7 years now, collected this from a family in upper Dolpo region in Nepal. This is not intentionally made for singing purpose rather it’s actually a domestic bird feeder called as Litté in Tibetan. I received this bowl as a gift from a very dear friend of my so kindly do not ask for the price as it is not for sale. When I played it for the first time, I felt something very special, and for no reason, I could actually feel sensations in my throat, belly and forehead, there, I knew it was something special. So after getting back to Kathmandu I was just checking frequencies of my other newly-made bowls I also happened to check the frequency of this bowl and I was shocked It was so precisely 666Hz. As we know the frequency of bowls changes slightly according to seasons so in the winter it sings 666Hz which is what Dolpo region actually is (Super Cold !!!) and in summer it wobbles between 666Hz to 665.5 Hz.. I am so happy to share this recording w
