Endless Knot

The endless knot or eternal knot is a symbolic knot and one of the Eight Auspicious Symbols. It is an important cultural marker in places significantly influenced by Tibetan Buddhism such as Tibet, Mongolia, Tuva, Kalmykia, and Buryatia. It is also sometimes found in Chinese art and used in Chinese knots.
The endless knot has been described as "an ancient symbol representing the interweaving of the Spiritual path, the flowing of Time and Movement within That Which is Eternal. All existence, it says, is bound by time and change, yet ultimately rests serenely within the Divine and the Eternal.
