Humanity is somewhat disempowered in not understanding its past, which is the origin and purpose of the human soul. There has not been a fixed time from which to reckon by which to measure history and saddled with the shortened chronology that is supposed to explain the entire unfoldment of the human race, a distorted reality has been created.
The spiritual path is one of forever peeling back layers of the conscious illusion and the mystery of human evolution is one of the greatest secrets yet to be fully revealed. Modern science and the secret sciences roughly concour on some of the larger cosmic cycles, Yet it is ironic on some that in the time scales for some of the modern sciences such as archeology and anthropology there is required a huge addition of time for the birth of civilization from 3k - 4k BC back to 18.5 million years.
Equating the esoteric record of time with the current accepted geological record there is a massive subtraction of time from around 65 million years during the jurrasic age down to around 25 - 28 million years of the esoteric doctrine.
Time is an illusion yet just as a human being has its allotted life span so do all other lives, plants, solar sytems, galaxies, races, civilizations and nations, all entities therefore have a measurable cycle in which to achieve certain goals in their evolutionary pattern.
