If there is a hint of force from one, the opposing side will try to negate it by using an equal maybe bigger opposite force, Therefore conflict occurs.
If there's lightning, let it hit the ground. If there's thunder, let the sound disperse through the sky. If there's water, let it flow. If there's fire, let it burn.
Not quite right. If you do not change it slightly, the threat may remain. If you let the attacker do exactly what they want, there is a chance they will succeed.
An aikidoka is that vacuum, that ground, or the ocean that the water will eventually flow into. Dispersing the negative energy into the universe, letting yang meets the ying, so there will be harmony.
As we are all still a beginner in understanding the universe itself, we cannot easily be what was written in the analogy above.
Or it may be a poor analogy.
So we have to let the fire burn out, let the lightning run its course, and let the water flow as it must. Hence the harder the attack, the harder the attacker falls, because the attacker must flow as the attacker must.
From the universe's point of view, there is no negative energy. The universe doesn't much care if you live or die. Is there such a thing as too much harmony for practice? Yes, if you are egotistical, or you prefer life to death.
