Hi!
yeh .. I think it's all food but you eat stuff that makes you feel 'lighter'
or if you choose to eat stuff that makes you feel heavy and yes denser to the light energy like Qi- Chi- Kundalini ..Prana... etc
Water and air are like liquid light
Sometimes in the past I felt like eating heavy food kept me more grounded but as I understand more about stuff like this I have gone back to just fish and seafood and a bit of occasional chicken ...
heres a few links on the Orch-OR stuff..
