Which enemy is harder to deal with, the one outside or the one within?
The enemy within is harder
An enemy outside can easily be got rid of. If you make his life difficult, he will go away. But the enemy within does not exit so easily. It takes much more force, sincerity, honesty and incisive action.
An outside enemy we can easily get rid of. The enemy within takes much more force, sincerity, honesty and incisive action.
