I was in Finland and Norway recently and felt that both countries resonate my Brow or Third Eye Chakra. In China, I had the same sensing that the place especially in Tibet, vibrated my upper chakra between my Third Eye and Crown. I traced back my memory bank to the time I was in America and remember it stirred my Solar Plexus, likely to indicate that it is operating predominantly at the Mental Plane, (My own country Singapore too have vibrations close to the Solar Plexus Chakra). There were some countries I had been to that had their vibrations stuck at the lower sacral and base chakra, Indonesia is one of them. Now, I am not sure whether it is the geographical differences or the people and their culture (or a combination of both at varying proportions) that causes the variation in the energy vibration.
