...in searching for meaning of the antakarana symbol, i consider the tibetan phurba, which resembles a three sided "tent stake" that has ritual significance in ideas related to grounding and anchoring...
the tip of a phurba in a way resembles a more basic shape, the tetrahedron, known as one of the most stable of shapes - its edges can be formed by a combination of three "7"s. this gets back to saturn being a planet of structure.

of course there are many marriages planned for 7/7/7, so here again saturn a planet of rings relates. one of my favorite references about rings is the penguin book of symbols. in some way i consider the wedding ring as a form of a more primitive hole stone - or holy stone, or "whole" stone - a circle as a simple symbol of unity.

another connection may be aleister crowley's work "777 and other qabalistic writings", though i can't speak personally of ever reading that work. the stable structure of the "tree of life" likely relates to embedded tetrahedral geometries.
