Saturn trine Jupiter
Outer circumstances and the flow of events make it easy for you to make clear decisions, see the road ahead, and move forward. Things seem to fall in place, and progress is easy. Be careful not to overextend or bite off more than you can chew.
Transiting Saturn trine or sextile your natal Jupiter. This is an opportunity to build something long lasting in your life. You are able to make steady progress but this combination puts an emphasis on stability in building into your life what you want. As a result, you are not likely to make fast leaps or advances. You are likely to have more patience and be balanced and pragmatic in implementing your ideas. It is a favorable time for business and entreprenurial enterprises. If you own a business, this is a period of steady and maintainable growth.
Transiting Saturn sextile or trine Jupiter
Your expectations and outlook on life are considerably more realistic now as you naturally seek balance between too negative and overeager attitudes. It's a strong time for realigning your projects and getting your life priorities straightened out. You are concerning yourself with the long term now, and practically preparing yourself for a better future.

Transiting Saturn in aspect to the North Node
When Saturn transits in aspect to the North Node, the manner in which you associate with others in terms of give-and-take and learning experiences, comes into question. Negative, greedy, or irritable attitudes towards others are things that you are learning to rid yourself of. You might meet mentors or those older or wiser than you who have something important to teach you. Hard aspects are associated with troublesome social relationships or withdrawal from socializing as part of a necessary process of personal growth. You are learning to rely on yourself, as well as to adopt a humbler approach to others.

Saturn Transits in Aspect to Natal Jupiter: Saturn and Jupiter are true opposites. Saturn contracts. Jupiter expands. Saturn is pessimism. Jupiter is optimism. When transiting Saturn makes an aspect to your natal Jupiter, the Jupiter effects tend to be curbed. Under the stress aspects (conjunction, square, and opposition) your optimism shuts off. If you have been getting by on “luck” for a while, the party is over. Time to pay the piper. As always with Saturn transits, check to see when this one is coming and plan ahead. If you have some project that is scheduled to be completed during a stressful aspect that Saturn will be making to your natal Jupiter, try to reschedule it. If you can’t, then put in overtime and work harder. Remember, Saturn is the planet of “Murphy’s Law”. If something can go wrong, it will go wrong, usually at the most inconvenient moment. Stressful Saturn transits are the most inconvenient moment. Transits with the harmonious aspects (sextile and trine) are generally good times to do extra work as well, but not because you have to. Most likely, you will want to. Progress will tend to be easier when Saturn makes a transiting trine or sextile to your natal Jupiter. You will be going in the same direction as with the stress aspects, but the road will not be as bumpy.
