Because of the precession of the equinoxes, the position of the stars in relation to the Earth slowly changes, moving through one sign of the zodiac every 2,100 years.

The Piscean Age reflects what has been called the “Christian Dispensation,” and perhaps its most obvious feature in this aspect is the dependence upon someone or something other than yourself for spiritual evolution. Dates given for the end of this age range from 1904 to later than 2200, but that does not mean that the effects of the change to the next era are not being felt.
