frm-octagon-planDefinition
The regular eight-sided plan — a TRANSITIONAL form 'made of equilateral lines and equal angles like the square, but tending (because of its multiplicity of lines and angles) in the direction of circularity'. Used 'for certain purposes', occasionally; its constructional difficulty makes octagonal rooms/buildings 'no more inherently stable (or popular) than circular ones'. Appears in the Śiva Liṅgam's octagonal mid-section (the realm between Earth and Heaven). [MODERN — Svoboda].

Prāṇa relevance
The square↔circle (Earth↔Air/prāṇa) transition embodied in one form; the geometric mediator of the line/curve continuum. Not independently traced to prāṇa beyond that mediation.
