shows a problem relating to father. no matter what the sun sign is it will be overshaddowed by the planet Saturn and take on those qualities of hard work, responsiblity, cautiousness, reserved, maybe bit of workaholic.
Sun conjunct Saturn
This is a rather sober aspect. Those born under a Sun conjunct Saturn aspect, in their youth, are humbled in some way such that they do not feel free to express their will in an outgoing and direct manner. As children, their expressions of their ego were thwarted, which led to some self-consciousness regarding self-expression. They were painfully aware that what they wanted, they didn't always get. As adults, they do not feel comfortable as the center of attention.
