Aryan is originally a spiritual title meaning someone who is extremely spiritually advanced and close to becoming a God. During the Golden Age Global Civilization, this word was commonly used to refer to white people, because there was a group of white Gods who physically traveled around the world and taught spiritual knowledge, knowledge of how to become a God, knowledge of farming, and knowledge of planning and development of cities. These were called Aryan because of their spiritual ranking, but also they were white and the local people receiving these messages were often not white. So the word used to refer to these specifically white Gods, Daemons, and Heroes, also became associated with the descriptions of them specifically being white. In the times of the Vedic stories, the Aryan Gods and Heroes were usually described as being pale white and having either red or blonde hair.
The spiritual term is true for any race, for any person who achieves this level of being close to becoming a God.
