A sextile links two planets that are 60° apart, usually in signs that share the same energetic polarity (both active or both receptive) without sharing an element — a gentler, more effortful cousin of the trine.
It's read as a genuine opportunity rather than automatic ease: the door is open, but unlike a trine, it takes a small deliberate step to actually walk through it. Left alone, a sextile's potential simply goes unused rather than causing friction.
