The endless knot or eternal knot is a symbolic knot found in Tibet and Mongolia. The motif is used in Tibetan Buddhism, and may also be found in Chinese art as one of the Eight Auspicious Symbols.
The endless knot has been described as an ancient symbol representing the interweaving of the spiritual path and 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.
Various interpretations of the symbol are the inter-twining of wisdom and compassion, and the interplay and interaction of the opposing forces in the dualistic world of manifestation, leading to their union, and ultimately to harmony in the universe. The Endless knot iconography also symbolises Samsara, or the endless cycle of suffering or birth, death and rebirth within Tibetan Buddhism.
Endless knots as mystic and mythological symbols have developed independently in various cultures. A well-known example is the various Celtic knots. Since the knot has no beginning or end it symbolizes infinite wisdom.
