In twin flame synastry, Eros, Psyche, Amor, Union, and Destinn are worth examining alongside the usual planetary aspects. Each asteroid describes a different part of the connection. Eros concerns sexual desire, Psyche points to a sense of knowing someone from another lifetime, Amor represents unconditional love, and Union concerns the desire to be together, even after a long separation.
The most interesting contacts are exact conjunctions with the other person’s Sun, Moon, Venus, Ascendant, or lunar nodes. For instance, Eros conjunct Psyche combines physical attraction with a deep emotional attachment, and Union conjunct the North Node suggests a relationship that plays an important role in both people’s lives.
