Understanding compatibility for these signs, therefore, requires a shift in perspective. It is not a matter of comparing hobbies or intellectual pursuits, but of plumbing the emotional and spiritual depths for resonance.

It is a bond built on unspoken understanding, where a glance can convey a novel's worth of emotion and silence can be a richer conversation than any spoken word.
