Energy of signs and planets is connected through aspects. They are relationships between two or more types of energies. Aspects show how energy manifests, transforms and how its issues must be overcome. Traditionally, aspects are divided into easy and challenging, major and minor. My experience in astrology has confirmed that there are no difficult aspects. They become such because of the quality/density of our energy. “Easy” aspects include sextile and trine and “challenging” aspects include square and opposition.
