Do not fight all the passions at once

He, then, who knows what is to his benefit should struggle to acquire this virtue before anything else, according to St. Basil the Great. For St. Basil advises us not to fight against all the passions at once ... Rather we should fight the passions one at a time, and start by patiently enduring whatever befalls us. This is right; for the person who lacks patient endurance will never be able to stand fast even in an ordinary battle, but will bring only flight and destruction upon himself and others by retreating.
