If Wyrd is karma seen through the narrative and ironic lens of Old English literature, yarn is karma in the way a Buddhist would use the word in a sentence. It is the simple mechanics of the universe: the endless interconnected causality of all existence.
The metaphor is a tapestry. Every single thing in reality, whatever we might consider a "thing" to be, is a thread, infinitely long and connected to every other thread. Yarn is the totality of these threads, all woven together in one vast, interconnected fabric. It is the structure of reality itself: the web of dependent origination that Buddhism describes, rendered in the image of the loom.
Where wyrd emphasises the ironic, personal, dramatic quality of causality, the way one's own doom unfolds with narrative elegance, yarn is concerned with the fabric as a whole. It is impersonal, mechanical, and total. Every action sends a vibration through the entire tapestry. Every cause has infinite effects.
The word "yarn" itself carries a double meaning in English: both the physical thread and the act of telling a story. Both senses are active here. Reality is a grand yarn, an orchestrated story woven from an infinity of threads, each one contributing to a pattern too vast for any single perspective to comprehend, yet coherent from the vantage point of Oneness.
