I am not sure I would have chosen the word "underworld" to describe these stages. As I understand it, each one is a stage of evolution--of the planet, life forms, consciousness. Now we approach the final stage recorded in the Mayan calendar.
The energy of the Universal Underworld moves us toward the establishment of a new consciousness--unity consciousness, which Calleman says will "transform all of human society" (from his lips to God's ears).
In every underworld of the calendar, time is broken into "days" and "nights"--seven days and six nights. The days and nights of the Galactic Underworld, the previous stage, endured for 360 each. Every year, give or take, we experienced a shift from day (the introduction of a new stage of the energy) to night (time for integration of that new stage) to day again.
From what we may understand of the Mayan calendar the unity consciousness will set an end to all forms of dominance of one human over another and especially those generated by the left brain. What this likely will mean is that instruments of dominance, such as the current financial system, weapons, national borders and many other structures upholding authority in this process will come to crumble as an effect of this unity consciousness coming into existence and so conclude with the birth of a new world where a divine harmony characterize the human relations. This end to dominance will also affect the relationship between the genders on a global scale that as a result will profoundly shift. Needless to say, there will never be any return to business as usual. Instead we will need to approach the birth of the new world consciously and with an intention of co-creating it in a positive sense and not just react to the various difficulties that lie ahead. I believe that such a collective intention of co-creating the new world will be the best way of easing the consequences of these difficulties.
The ninth and final stage of the Mayan calendar is comprised of days and nights less than three weeks in duration. Every 20 Gregorian calendar days we will switch from day to night in the Mayan framework.
If it feels to you like everything is speeding up, that's because it is.
Welcome to Day One. Let the ride begin.
