Like being hoisted by our own petard, all of our carefully laid plans backfire and explode in our face. This does not ask us to avoid making plans, afterall you are the master of your own destiny. This does mean that our plans are typically serve only ourselves to the detriment of others. This verse is saying that those self-serving plans are actually detrimental to ourselves, not to others.
The title of the text ‘Wheel-Weapon Mind Training’ brings to mind a boomerang. We throw the weapon to a target that serves our own purpose, but the the boomerang circles back, hitting ourselves.
