the endless knot
The endless knot is one of the eight fortunate symbols in Tibetan Buddhism. It has many meanings.
It is a pattern that is closed in on itself with no gaps, signifying the interrelatedness of everything.
It shows that the apparent disharmony and contradictoriness of the world we see is, seen properly, an illusion, disguising a world that is balanced, complete, and utterly interconnected.
In particular, it signifies the union of compassion and wisdom: that they are two aspects of the same thing.
When given as a gift, it indicates a deep karmic connection between giver and receiver, but in the context of a universe in which, seen with the eye of enlightement, all the scattered and disparate components are similarly, intricately, linked.
At the level of giver and receiver, it says “I love you.” At the level of the consciousness of the Buddha mind, it says “love.”
