In the mahayana tradition we experience a sense of gentleness toward ourselves, and a sense of friendliness to others begins to arise. That friendliness or compassion is known in Tibetan as nyingje, which literally means "noble heart." We are willing to commit ourselves to working with all sentient beings. But before we actually launch into that project, we first need a lot of training.
The obstacle to becoming a mahayanist is not having enough sympathy for others and for oneself--that is the basic point. And that problem can be dealt with by practical training, which is known as lojong practice, "training the mind." That training gives us a path, a way to work with our crude and literal and raw and rugged styles, a way to become good mahayanists. ~ Training the Mind and Cultivating Loving Kindness by Chögyam Trungpa
