I have some questions on the vow. First, has to do with the mind. What if one has an angry thought, is that violence. Or, if one were to think only for a moment a thought of harm in anger. Then, has the vow been broken?
Second, if one likes to play video games. Lets say something like gears of war. The game depicts violence, obviously, with a title like gears of war. Does, this violate the vow. It is not say violence with emotion or malicious intent but does that violate the vow?
Basically, if one takes the vow then one cannot get angry because that may lead to a violation of the vow, in thought, and unfortunately, but this may often be the case, one may have to give up some things.
