It is my belief...and I could be way off- so be careful..
that the celestial bodies in the heavens are naturally in sync with certain types of people on Earth that by their own intuition follow an internal clock. This may not be true for Women within "civilization" who are constantly exposed to artificial light and electricity.
But it is very true for Women who live out in the natural world beyond artificial light whose bodies are influenced by the levels of moonlight. Living with such Women would expose one to "lunar time." Overall not every Woman in civilization are responding to the cycle of the Moon every 28 days, but some are. What is interesting is that if Women are working together or living together their cycles will become insync with the most dominant "mother" female within the group. Showing that it's also possible for a actually "person" to act and behave as a celestial body- just based on their level of consciousness, which happens to be the only difference between a Woman who is "motherly" and a Woman who is "daughterly."
Also interesting...Men don't have "menstrual" cycles..not that we know of, yet Men also become insync with the most dominant Father consciousness within their group. This phenomenon is more carefully observed in the wild especially with Lion prides. Men on the other hand have to literally "fight" to become that dominant figure through a series of challenges and battles. In fact because of this for Males "time" is like a form of currency. For centuries Males no matter how much wealth and power they have amassed have been accused of not spending enough "time."
We adapt into systems of time, and we assimilate into them, following the rituals of the most dominant among our groups and tribes.
You can create your own calendar or system of time by acknowledging your dominant bodies of energy that influence your physically and mentally right here on Earth. For example people who have strong creative abilities, intuitions, dream abilities, psychic abilities etc., are a strong dominant force on the planet for me...which explains why I go to bed when most people are waking up- 5am-7am in the morning. When some of you are just having lunch, I'm waking up. When some people are leaving work I'm starting work. I'm constantly interacting with heavy thinkers and artists. I set my clock based upon these meetings. We keep Owl time, we hunt at night when the Moon is out. Therefore we also control the waters and psychic energy that is more abundant at night.
Now If I really wanted to change my life.....I'd wake up when these birds started singing.
