elizabeth,
If you are experiencing Hum, please check for possible ground
loops. While existential resonances are par for the course of the human
species, spillover into the electronic food chain is not.
Have all chakra planes been properly balanced? Akashic links
cleansed? Is there proper thangka/thorgum/karma distribution in the listening
space? And what can you tell us about the condition of the solar plexus? We
can't best you, unless you help us to best you better...
