Mercury will pass very close to the Sun in the sky as its orbit carries it around the far side of the solar system from the Earth. If a planet is right at the core of the Sun, then it is utterly consumed and this is called being ‘cazimi’. Mercury going into the heart of the Sun means that for a small window of time Mercury is super powered while sitting on the royal throne.
Mercury and the Sun together in Libra could give us insights as to where things might have gotten unbalanced, unfair, unjust and, the solutions needed to rectify the scales.
The Sun in Libra is considered in its ”fall” and pretty weak. It’s also the time of the year when things are dying as opposed to coming to life. With Mercury conjunct the Sun today I imagine realization and clarity will tend to be more around endings, death and decay as oppose to new beginnings and there is a definite liminal quality to this time of the year.
