How would you interpret this stellium?
transiting saturn is about to change signs into scorpio for its 2.5year stay and will go over sun first and then the other two, which may present challenges. Personally I prefer a synastry bi wheel…
Composite Sun Conjunct Composite Saturn “Sun conjunct Saturn is a very powerful aspect in a composite chart. It indicates that you have come together to have an important learning experience. Nothing else matters very much, really. Your relationship may or may not be long lasting or ultimately satisfying in terms of what you now expect of it. The dynamics of the relationship will change your expectations.
The experience of this relationship may expose you to truths about yourselves that you would rather not face, which may cause you to be discouraged. But instead of reacting negatively, try to learn about yourselves, even about your shortcomings and weaknesses. The point is not to judge yourselves or each other, but to see clearly and with detachment and then try to make changes where necessary.
In many respects you may find this relationship confining and limiting. You must ask yourselves whether the relationship is giving you a necessary discipline that you would not otherwise have. Or is it cutting off legitimate self expression that is really an intrinsic part of you? You may be inclined to feel that the latter is the case, but be very careful. It may well be that you do need this discipline and that you are not facing your responsibilities. If you need this experience, the relationship may last a lifetime. But if it is really too confining, it will probably not last very long. A Sun Saturn conjunction can operate either way."
“Composite Sun Conjunct Composite Mars Composite Sun conjunct Mars is a very energetic combination. A relationship with this aspect in the composite chart is not likely to be entirely peaceful and quiet, but it can be very creative. This relationship will arouse strong energies within you, energies that can be used for getting a great deal of work done or for making changes within yourselves.
You will have many discussions about your relationships or other subjects that will border on or actually be fights. However, this is not as negative as it sounds, for these “battles” can help to clear the air and prevent serious strains from developing. If you have this aspect in your composite chart, it is important that you express these energies. Do not suppress your legitimate angers and complaints because of a misplaced desire for peace and quiet. This relationship can grow through creative conflict. If you do suppress your anger or express it indirectly, the relationship could become very uncomfortable or turn into an endless stream of arguments.
Since Sun conjunct Mars is an indication of physical vitality, you should take part in vigorous physical activity together whenever possible.
This is a tricky aspect to handle in a business or professional relationship.It can be an indicator that you will work well together and accomplish much with dynamic vigour. But if the energy between you is very strong, it can indicate disputes, conflicts and disagreements, as well as destructive ego competition."
