The waves of samsara reveal a brachistochrone cut; no amount of kata can prepare one for this work. A change of lineage abandons all forms, and its work is beyond, the cut operation expands the warp shed for a join operation. The secret to sword, cut and stick, folding folding. Warp and weft, in and yo. Realize emptiness.
The target, samsara, is alive, is moving, is changing, even the shapes change, there are transformations, there are flows, there are slows, and increases, do not be confused by kata, it is the mastery of manifold change, movement and stillness that is the ground of awakening.
