The Valknot is Wodin's symbol. Its three entwined triangles represent many things, including the knot around the hanged man's neck, the three vertical levels of the nine worlds, and the interpenetration of all the realms of being by one another. Odin's knot symbolises His nature as that which inspirits and unites all things. He is the dynamic whole, and the energy within matter. The Valknot is a depiction of the nine worlds, separate yet intimately bound, and also represents the many soul-parts that make up a conscious being. All of these are knotted to each other, and have His Spirit in common. To wear the valknot in modern times has come to symbolise that the wearer has given him/herself to Wodin, and acknowledges an inseparable bond with Him. The knot can mean an oath, but is also can mean the bond of spiritual Love, and the windings of Wyrd. The Native American expression "It is a good day to die" is exactly the state of mind and will signified by the wearing of the Valknot. Wodin is known as the both the Fetterer, and the Fetter-loosener. These names refer to His ability to tie and untie the threads of Wyrd, and His famed power to set and release bonds, such as the "battle fetter". This too is a meaning of Odin's knot. Another triune Wodenic symbol akin to the Valknot is commonly called "Odhroerir": three crossed drinking horns. Found carved on cultic stones, just as valknots were, these three united horns represent the three vessels that contained the Mead of Poetry, and thus Odhr, Odin's gift of poetic inspiration. I think that it is possible that the three Runic Aettir ("families", in groups of 8) are also represented by the Valknot. The number nine, sacred to Odin, is also the number of points on the Valknot. Not surprisingly, one of the meanings of the rune hagalaz, the ninth rune, is "source of all rune staves".
