I just learned that I have my Saturn at 18 degrees, which I have herd may be the degree of sickness or bad luck. In my 10th house.
Any insight?
First of all did you read the sticky, in this sub-forum for Degree Symbols, about understanding the enumeration of the degrees?
I doubt that you did otherwise your query would've been worded correctly.
Is Saturn in the 18th degree [never mind what Sign] or is it in fact in the 19th degree?
If your natal chart shows Saturn to be at exactly 18° 00' 00", then you may say that it is AT 18 degrees.. Anything more than that is, in fact, in the 19th degree, anything less, down to, and including 17° 00' 01", is in fact in the 18th degree.
Secondly, what you are asking about is not about Degree Symbols, but rather the alleged nature of a certain degree... but as it seems this is a mistake that is made about once or twice a year here at this forum, and you are obviously newly arrived... all I have to say any further is, Welcome aboard. If you have any similar such questions in the future try looking through the various other sub-forums here at AW and see if one of them might be appropriate?
If you don't think there is one, then might I suggest posting such a question in one of the natal astrology sub forums?
I'm not a moderator here, nor do I have any connection with the administration, but Degree Symbols is kind of my "specialty", others might say it to only be an obsession, but whatever one might wish to call it, I do like to see that this sub-forum doesn't get cluttered up with threads that don't really belong here. That way the relevant threads don't get buried further back into relative obscurity.
I do have an opinion, or actually more of a comment in answer, that comes from nearly 38 years of determined astrological studies and a lifetime of experience with matters concerning spirituality and humankinds' existence, to your question that may be of help, however?
That is, there is nothing in the Heavens put there by our Creator that was placed there with the intent of being malevolently harmful.
What does cause us grief is due to our own karmic indebtedness and there are those objects, and aspects, that will mete that out.
I hope that I have been of some help to you towards becoming greater in astrological knowledge and becoming more adept at becoming, or being, an astrologer yourself.
Fear not... as for what my signature line says is quite true.
