Purge your demons = gain knowledge

The man who purges himself daily can achieve anything he believes. For in so doing he will know himself better than the demons that tempt him. And knowledge is power.

Don't lean on anyone else for strength, find your own strength.

In times of trouble no one will save you but yourself. There are only a handful of friends who will stand up for your honour when the world has abandoned you. Only in suffering will you find these friends.
