Inner peace, like local peace, also depends on circumstances and environment. It's very difficult to maintain peace when you're too close to conflicts or those who cause them. A sense of injustice naturally arises, as we seek to apply common sense, kindness, and proportionality. Personally, I avoid unnecessary arguments and conflicts, I'm a more reserved person, but recently, it's been hurting and irritating to see someone close to me compulsively lie, criticize, and take advantage of others, to the point of irritating everyone and leaving them without what's theirs.
