The Celtic knot symbol, is also referred to as the mystic knot, or the endless knot. In viewing these beautiful knots, we cannot see a beginning or an end, and therefore we are reminded of the timeless nature of our spirit. This translation harkens to our most primal selves as we contemplate the infinite cycles of birth and rebirth in both physical and ethereal realms.
A less spiritual representation is also related to the knot's endless nature. Due to its infinite path, the Celtic knot can represent an uninterrupted life cycle. Some may use this symbol as a charm of sorts warding against sickness or setbacks that night interfere with an otherwise calm and stable life.
