“Just as compassion is the wish that all sentient beings be free of suffering, loving-kindness is the wish that all may enjoy happiness. As with compassion, when cultivating loving-kindness it is important to start by taking a specific individual as a focus of our meditation, and we then extend the scope of our concern further and further, to eventually encompass and embrace all sentient beings. Again, we begin by taking a neutral person, a person who inspires no strong feelings in us, as our object of meditation. We then extend this meditation to individual friends and family members and, ultimately, our particular enemies.
We must use a real individual as the focus of our meditation, and then enhance our compassion and loving-kindness toward that person so that we can really experience compassion and loving-kindness toward others. We work on one person at a time.”
― His Holiness the Dalai Lama
