Reacting with compassion and kindness to someone who is unkind, cruel, selfish or angry take practice and patience. It’s also healthy for you.
Fear is the path to the dark side…fear leads to anger…anger leads to hate…hate leads to suffering – Yoda in The Phantom Menace.
Most of the time sadness and fear hides beneath hate and anger. Hatred, violence, and anger are the symptoms, but sadness and fear are the cause. Compassion and kindness is the antidote for the underlying cause.
