Those who truly understand it are unique; refrain from giving it false names.

This couplet reminds us that the ultimate truth, or the divine, is understood differently by those who truly know it. It's a knowing that goes beyond ordinary labels. The second line urges us not to give it false or misleading names. It means we shouldn't try to confine or define the profound with our limited human concepts, names, or doctrines, which can sometimes distort its true nature. Instead, it encourages a deeper, more authentic understanding that transcends conventional naming. It's about respecting the ineffable and acknowledging that true wisdom comes from a unique realization, not from superficial categorization.
