Quincunx
The quincunx is a “neutral aspect”: it doesn’t signify harmony or tension, but it does indicate a difficult to realize potential.
A quincunx can involve an effort to reconcile two planets’ meanings in the chart, but even when the initial signs seem positive, there is no guarantee of success. In the end, it may not prove possible to truly integrate the energies involved. For example, if Venus and Mars stand in quincunx to one another a person may try to boost her self-confidence by investing large amounts of energy (Mars) in order to achieve aesthetic goals (Venus). But she may feel that the energy invested never produces the desired results. For this reason the quincunx is thought to be difficult to deal with and is often referred to as an aspect of desire or longing. On the other hand it shows important themes which the horoscope owner must face. The lack of success can be an impetus to consider and possibly change established patterns of behaviour. In this sense the quincunx hints at new possibilities.
These patterns of tension that are relatively minor, yet persistent and difficult to resolve lead to this aspect’s second meaning: adjustment. It is often simply easier to live with a source of disappointment or aggravation than to take action to try to resolve it. Perhaps the person feels the present outcome is inevitable.
Part of the problem is that it is difficult for a third planet, natal or by transit, to offer resolution. A third planet might sextile or trine one of the quincunx planets, yet square the other one. Resolution is best handled by identifying the basic needs of each planet and looking for non-stressful activities that draw on both their strengths.
