Practicing compassion, caring for others and sharing their problems, lays the foundation for a meaningful life, not only at the level of the individual, family or community, but also for humanity as a whole.
Karma means action and action motivated by compassion is good. To complain that what happens to you is just the result of your karma is lazy. Instead, confidently recalling the advice that, "You are your own master," you can change what happens by taking action.
