The elements you lack in your natal chart, or those marked by tension, represent your shadow sides.
For many individuals, on an energetic and subconscious level, encountering someone who embodies an element you are weak in can provoke a reaction—one that may seek to diminish that person's expression.
When someone shares elements with you but also displays those you lack, and those elements form no positive aspects in your synastry, they may seem inconsistent or untrustworthy. You might perceive them as changing or irritable, largely because you are reacting to that energy.
The projection dimension tends to be more pronounced if you have strong Moon or Cancer placements, or if your chart lacks Capricorn or Saturn aspects.
Those with all elements present may continually attract a range of people, yet eventually distance them, as the energy’s diversity hinders stable connection—especially if those involved remain unaware of their own reactions.
Triggers and shadow sides are not limited to past experiences and trauma; some are fundamentally elemental in nature.
