some more sencible questions.
Natal astrology profiles who you are... what talents/weakensses you have. It gives a range of possibilites because people can use their talents differently... one arty person would do music, another paint, another cook etc...
An analogy.....If you say that Natal astrology says you have a knee, predictive astrology identifies the time when someone kicks you knee and hit s reflex action. Central tendancies of the Natal usually identifies if it will be stressful or not, or simply a major point in your life.
Predictive astrology is at it's best with BIG stuff. Day to day are a bit lame and a bit wishy washy. Big stuff is usually predicted by the slow planets (ie major life transits). These identify major events in your life. These heavier impacting planets work slowly so there is likely to be 8-10 week periords where tention build and events play out. The transiting planet starts to aspect the natal planet, makes the angle then moves on. IT then reverses back over the planet (usually at the strongest point) and then turns direct again and scoots on by. So slower planets usually make 3 hits of the natal planet, the middle one is often the strongest/has the most impact - although not always.
I once read for a skeptic on the plane, and he more or less said he thought it was rott. I correctly identified the preiod he was divorced in, and that h had fairly recently met the love of his life, saying she was a teacher or laywer... He was bowled over.
Can you predict life event for the whole of a period of life, well yes and no... You can see when things will be challenging. Tough aspects in childhood can leave hevier scars on a person or none at all because the child learns to deal with it. If they receive the same transit in their 30's it has a bigger impact on them.
Some planets make a number of cycles in a persons life, ou may have heard of Saturn Return, happening around 28.5 years. This is the gateway to true adulthood, this happens again in 28.5 years time or there abouts. The peson learns and matures and reacts differently even to th same transit...
Say for instance a person is born with viloence or abuse hall marked in their Natal chart, often the experience something bad in childhood or teen years. They may then go on to marry someone abusive and then leave them. They then open a refuse or something for people who have suffered from abuse. They are using their "abuse aspect" productively to help others... this usually stops the abuse happening directly to them.
Hopefully that makes sence
