Alternative interpretations of a planetary aspect
Posted on Quora
We assume the fastest planet is the first to be considered in the natal charts from a traditional point of view. On the other hand, the strict application of the rule could be misleading in interpreting the aspect.
In the example above, Mars square Uranus will generally mean a decision to act due to a sudden, unpredictable, and potentially damaging event. On the contrary, Uranus squared to Mars will point to an instinctive reaction that could damage the evolutionary potential and prospects. This binary interpretation allows you to correctly judge all the situation facts while keeping an open mind.
Much depends on the strength of the planets of the natal chart and complementary aspects: the stronger the planet, the greater the impact on the weaker one. In this case, the ruling planet will prevail in interpreting the aspect.
