The eternity love knot, sometimes known as an endless knot, is a closed, looping decoration that is composed of intertwining lines in several overlapping forms. It is named the eternity knot or the endless knot because it does not have a beginning or end.
The endless knot is featured in numerous variations across a broad range of cultures and belief systems. It is frequently seen in Celtic arrangements and decorations, and it is even found in Buddhist and Hindu motifs. There are many cultural interpretations of the knot, and its infinite design lends to some theories of endlessness behind certain major creeds, such as Buddhism.
