It can predict when climactic events will happen, the moments of terror that punctuate the boredom of life, but it can't tell you the content of your life. It can't tell you what will happen. Astrology can tell you in advance that any event that occurs at a particular time will have a specific emotional meaning. That meaning is independent of the nature of the event. Sometimes a family member will die, but you will experience the bereavement years later under the appropriate transit.
Winter solstice is notorious for triggering such delayed catharsis.
That is why those who embark on an initiatory path need to learn astrology. No one outside your own mind can read your chart for you - any more than they can read your cards for you. They aren't you. They can't possibly know the true inner meaning of an event for your own soul. At this Millennium, we have a very large number of souls toiling hard up their own initiatory paths - a veritable army of seekers ready for this advanced initiation of the Fixed Grand Cross.
