A song by Alfred Yucel – ‘Agartha’. The song sings Agartha is ‘heaven is a place on earth’, though it is actually very deep inside it. Some say Agartha/Shambala is inhabited by large numbers of reptilians, so if venturing into underground tunnels to find it, take great care. I suggest you don’t, as although there are said to be some very high viration spiritual beings there, not sure explorers will get far enough into it to find them. See the inm.tv group Hollow Earth.
