I like to find a theme in a horoscope, since my experience is that we through reincarnation are learning lessons and intergrating wisdom from our path.
We can't learn everything in one life, so that's why the horoscope tells us what's important to focus on. Some things in the horoscope are tools in my opinion, and other are challenges and lessons.
To know if your saturn/jupiter conjunction is important to you (as a lesson and direction), or is more like a tool or a subtle energy, I'll have to look at the rest of the horoscope.
But Saturn, as a karmic planet, is important for those who have come a long way in their development of consciousness....and as the strict guardian to the outer planets and the divine and collective source, it stands for the karmic lessons we have to learn to get through the gate. That's why many people see it as the devil, since it's so severe as our karmic ruler.
For people who live a more simple spiritual life (young souls), Saturn is often used as a tool for personal power.
Saturn in the 8th house, tells me that you are at a point in your journey where you are going through a transformation with great powers. It may be with some form of crisis. It's the house of death and sexuality. When 12th house (the last waterhouse) gives the lessons through isolation. loneliness and dissolving effects, the 8th house transform our personality through crisis.
It's obvious that you are well developed, since this tranformation comes from within through psychology, the occult and similar. On a more simple level, you may have used Saturn for personal power. Like a warlord or a Don Juan....
Jupiter tells me that you have great tool for exploring and develop your new insight and karma, and that this position may give you happiness in the 8th house' character. I guess you like to read psychology and be at this forum
The position in Libra wants balance and a use of common sense.
Well, this is how I see this conjunction. Hope it makes sense
