3 weapons to fight the nafs

The battle against the nafs (lower, egoic self) isn't a joke.  Your eternal life and worldly life depend on it.  Fortunately, in my travels I have come across some weapons that have aided me on my personal spiritual journey of being much more aware of the tricks my nafs is trying to play on me.  As a result, I've dropped a load of psychological suffering, much of which I wasn't even aware existed, until it was gone. I never realised it's possible to go for hours and even days with virtually no thoughts - certainly none that create anxiety, anger or depression.
