Celtic knots are also known as 'endless knots' because a true Celtic knot has no beginning and no end: Tracing its path goes on forever – a symbol of eternity and the never-ending cycles of life.
The complexity of a Celtic knot is like the interlacing of a ribbon endlessly within itself: Over and under, back and forth, forever and ever. It's perfect as a metaphor for Life and the physical and spiritual interdependence among people and all living creatures.
Together, the two meanings of eternity and interdependence create an even more powerful symbol for love, especially when it is made of two Celtic knots woven together to become one. Such a knot represents two souls forever in love, friendship or loyalty.
