When throwing pebbles into the well, the ripples are unlikely to return to you as a tsunami. What is more likely is that you disturb the equilibrium of the well. This disturbance is good- if equilibrium results in stasis then the result is death. A balanced flow of force within equilibrium is healthy, as long as there remains an energy flow and exchange.
The true skill rests in being able to throw the pebble so that the ripples in fabric return to you in a positive state.
