A warrior goes mad with battle lust.
A day to be aware of your inner motivations. The “Berserker” has a fine reputation and honourable history. They turn battles. They lose battles. Fore warned is fore armed. Check your motivations and, in particular, check where you feel anger within your body. To do this, drop into a meditative state and scan your body looking for where the anger resides. The Berserker would access this place, either righteous anger or any other kind and channel that into battle lust. You do not need to direct your anger towards this aim, necessarily. You can rechannel it towards more appropriate goals. But until you can find that anger, it will erupt where you do not it to. Channeled, directed and understood your anger can be an ally.
