You cannot remove an aspect from your natal chart — it is a permanent part of your chart. What you can do is transmute the energy by raising the level of expression. A square that manifests as chronic frustration at low awareness becomes an unstoppable drive to succeed at high awareness. An opposition that creates constant push-pull in relationships becomes a remarkable ability to hold two perspectives simultaneously. The energy remains; how you use it evolves over your lifetime.

When transiting planets form angles to either your natal Mercury or South Node, the entire aspect is triggered and both planets vibrate simultaneously.

A very tight aspect is likely one of the defining features of your personality.

Integration, not suppression of either planet, is the goal.
