We often use the expression “take care” to express our concern for the wellbeing of others. But whenever we become angry or generate negative emotions, it amounts to self-harm, to failing to take care of oneself. So every time you lose your temper, you harm yourself. There is no pill we can take to eliminate anger and negative emotions, so we have to rely on our own ability to change our mental and emotional habits; and by changing the way we think, we can transform the world.
