「Using hands with stones」to clear soil of rocks in order to make it tillable farmland, but doing so does not require much talent. Or, remove something by「rubbing with a stone.」Frankly, neither rubbing the ground with any size of a stone, nor removing protruding rocks will break up the soil much.
　「Using talented hands on testicles」and「prepare for array of sliding heads, dammed」to CLEAR A SOIL PATHWAY, to BREAK UP into chunks and REOPEN ACCESS, to EXPAND and OPEN UP a sphincter and the lower colon region prior to some group activity: PUSHING SOMETHING WITH ONE'S HAND and forcing it into the plugged hole until the hole can be rubbed with one's stones ('all-in' mode), TRAILBLAZING (a blazing, burning trail), PATHFINDING (finding the path), COLONIZING (dwelling in the colon). Elements can also be seen as「stones, testicles in horizontal motion with streaming repeatedly」or「talented person standing with line of in-and-out side-to-side.」
　「Confiscate array of sliding heads」and「hand use on testicles」also may refer to emasculation (cutting off the genitals) of one's enemies, fallen corpses, and/or captured soldiers to prevent further breeding or just for the entertainment value of torturing folks to death by watching them slowly bleeding out with torture.
　Given external meanings suggest clearing land, but notice no 'land' elements are included. CLEARING THE LAND OF ONE'S ENEMIES is possible, a practice apparently perfected by Ioseb Besarionis dze Jughashvili who later changed his name to Smokin' Joe Stalin (meaning「man of steel」), perhaps because it was easier to spell, or, he admired supermen. Anally raping the vanquished has long been a tradition of human war culture and when establishing imperial colonies for exploitation.
