From "The Lost art of Compassion" by Lorne Ladner
This brings me back to the earlier question of what constitutes a good, happy, meaningful life. When you ask Westerners this question, some answer based on external accomplishments such as gaining a certain amount of wealth, popularity, sensual pleasure, comfort and social standing.
Others answer on a more deeply interpersonal level, focusing on their relationships with family and friends and on making some significant contribution to the world. It's extremely rare for anyone - even Western psychotherapists - to answer this question psychologically. The Buddhist response to this question is deeply psychological: Buddhism asserts that a good, happy life is determined not by anything external but rather by the quality of our minds and hearts in each moment of life. Regardless of what we do or don't do externally, a life spent cultivating wisdom and compassion is a good life.
At first, trying to use an argument as an opportunity to develop compassion and find joy seems a bit strange. Someone in your life approaches you in a provocative, agitated, unreasonable annoying way. You immediately think, "Oh, good, this is my opportunity. Here's an argument starting. Now I can really practice compassion!"
When you're just getting started, you'll be of two minds about the situation. Based on old habits, part of you will want the person to stop being difficult and to act kind and friendly. The part of you that is happy to find this opportunity initially may seem weak or less than genuine. That's alright; it just means that you're not yet accustomed to practicing compassion and inner disarmament. Lama Zopa Rinpoche advises us that when you get good at this practice, the thought of enjoying such challenges will arise as naturally and joyfully as the thought of liking ice cream or chocolate. It all depends on what you're accustomed to.
"Often it is difficult people who are suffering the most and are therefore most in need of compassion."
"Perhaps some parts of ourselves that we see as normal and essential to who we are in fact block us from being more compassionate, creative, content and joyful than we've yet imagined we could be."
"His Holiness the Dalai Lama often notes that in order to avert war and bring about disarmament in the world we must begin by effecting an inner disarmament."
"By spending time regularly for months or years imagining how they received limitless love & kindness over infinite expanses of time, meditators gradually develop an inexhaustible sense of gratitude, love, affection & inner wealth."
"If you're sincerely interested in being a more loving, good-hearted person then it can be particularly helpful at the beginning to recognise that it's mainly through your practice with difficult people that you will become confident that your inner development is bearing fruit."
