The following is a description of the Buddha’s teachings on the four qualities of love, from the first chapter of Teachings on Love, written by Thich Nhat Hanh …

“Happiness is only possible with true love. True love has the power to heal and transform the situation around us and bring a deep meaning to our lives. There are people who understand the nature of true love and how to generate and nurture it. The teachings on love given by the Buddha are clear, scientific, and applicable. Every one of us can benefit from these teachings.

During the lifetime of the Buddha, those of the Brahmanic faith prayed that after death they would go to Heaven to dwell eternally with Brahma, the universal God. One day a Brahman man asked the Buddha, “What can I do to be sure that I will be with Brahma after I die?” and the Buddha replied, “As Brahma is the source of Love, to dwell with him you must practice the Brahmaviharas—love, compassion, joy, and equanimity.”

A vihara is an abode or a dwelling place. Love in Sanskrit is maitri; in Pali it is metta. Compassion is karuna in both languages. Joy is mudita. Equanimity is upeksha in Sanskrit and upekkha in Pali. The Brahmaviharas are the four elements of true love. They are called “immeasurable,” because if you practice them, they will grow in you every day until they embrace the whole world. You will become happier, and everyone around you will become happier, also.

The Buddha respected people’s desire to practice their own faith, so he answered the Brahman’s question in a way that encouraged him to do so. If you enjoy sitting meditation, practice sitting meditation. If you enjoy walking meditation, practice walking meditation. But preserve your Jewish, Christian, or Muslim roots. That is the way to continue the Buddha’s spirit. If you are cut off from your roots, you cannot be happy.

If we learn ways to practice love, compassion, joy, and equanimity, we will know how to heal the illnesses of anger, sorrow, insecurity, sadness, hatred, loneliness, and unhealthy attachments… Love, compassion, joy, and equanimity are the very nature of an enlightened person. They are the four aspects of true love within ourselves and within everyone and everything.
