Loving-kindness and compassion, allow us to open our hearts fully to the world.
Loving-kindness and compassion protect us, and protect others as well. The Buddha taught that these qualities spontaneously bring benefit, just like a wish-fulfilling jewel, and that if our minds are filled with aggression and anger, not only will we be unable to help ourselves, we will not be able to help anyone else either. We will not be able to benefit ourselves in this life or in future lives.
Lets take a simple example:
The person with loving-kindness and compassion in their heart would look out and see nice people, good people. They would look and say, “Oh, what a nice person, what a good person.” They would be able to keep company with anyone and be harmonious with anyone in any situation.
The narrow-minded person with a mind filled with pride would not be able to get along with many people because they would see faults in everyone. Not only that; they would see small faults as very big faults – for instance, when we get into fights over very small, menial things.
So, which one do you want to be?
