Anger is of no value, why would you want to conquer something that holds no value.
Forget about conquering something that doesn't exist
It's only at times we get angry. It comes from with in us so if you ask yourself now it's probably not there which means it's not existent until we create it.
Sometimes we become angered but there is no sense in this, as there is enough unpleasantness from outside sources causing harm we don't have to harm ourselves!
When we get angry we cause more harm than good, if we focus the same amount of energy on something more valuable to your health the outcome is always much better.
From with in we have to take responsibility for our own well being! Look after our health with our eyes open!
