from Q&A with KnAThe instruction for the seat is concrete and ancient. On a clean spot, neither too high nor too low, one lays first kuśa grass, then a deer-skin (ajina) upon it, then a cloth (caila) on top. The three layers insulate the seated body — grass, hide, cloth — giving a firm, dry, steady base that neither chills nor tires the body over long sittings. The detail matters because the BG's meditation is embodied: comfort and stability of the seat are the ground on which stability of the mind is built.
