Sun conjunct the South node in Cap in the 12th...
I see two kind of intense things, happening at the same time. And kind conflicting, internally.
The South node in Cap in the 12th is a deep, underlying certainty that things will be alright, work out OK, because of all of the power your soul has accrued from past incarnations. You were a very hard worker and you had a lot of power in past lives.
And yet, the Sun in the 12th conjunct that South Node, brings in a different element. It can be a blanket of hopelessness or depression, and a vague feeling that things are too difficult and the 'world' is working against you sometimes.
So these two distinct feelings are in conflict and so internally you may have an inner battle.
One of a deep sense of wisdom and knowing and a belief that everything will be okay because of your faith and strength.
And simultaneously, inner fears and uncertainty that bring a sense of depression.
The Sun and South Node kind of battle each other. The Sun is light and strength and growth and the South Node is indicative of our past, and battles with shortcomings, etc. And also the soul growth from past endeavors...
So the struggle is real.
And you would be very much an empath and someone who could really see into someones soul.
