Everyone falls asleep. Sleep seems necessary for human existence... one can only go so long before sleep takes one over. Where is the 'over' to which sleep takes?
Why do we say 'fall' to sleep? A curious choice of words is it not? In the ancient Chinese wisdom of the I Ching, the time of sleep is related to the image of a steep precipitous waterfall. It is as if the stream of conscious awareness reaches a ledge... a threshold of consciousness... and then plummets over a steep abyss into a dark and deep unknown.
And what do we, collectively as living human beings find 'there' over the abyss?
Archaic wisdom from every cultural wisdom tradition on earth says we find the 'place' where our ancestors.... those who have gone before, seen and experienced much... dwell.
So, by way of attempting an answer to "Where do you go when you fall asleep?", the Sabian symbol for Aquarius 5 says, "into the arms of our ancestors".
In waking life this can be experienced too. It shows in a willingness to leap, as if one were to leap off the edge of the known world. The opposing Leo degree is nicknamed (by me) the 'Geronimo!' degree. That is, one just says 'Geronimo!' and jumps.
The only other option is vertigo... and that is no fun at all.
The degree 5 Aquarius suggests favorable outcomes, creative genius, and a knack for pulling things off. With Jupiter conjoined with the Sun today (January 23-24, 2009) the enthused optimism for success is really OTW (out of this world!).
