May I be happy. May I be well. May I be safe. May I be peaceful and at ease.
While you say these phrases, allow yourself to sink into the intentions they express. Loving-kindness meditation consists primarily of connecting to the intention of wishing ourselves or others happiness. However, if feelings of warmth, friendliness, or love arise in the body or mind, connect to them, allowing them to grow as you repeat the phrases. As an aid to the meditation, you might hold an image of yourself in your mind’s eye. This helps reinforce the intentions expressed in the phrases.
After a period of directing loving-kindness toward yourself, bring to mind a friend or someone in your life who has deeply cared for you.
Then slowly repeat phrases of loving-kindness toward them:
May you be happy. May you be well. May you be safe. May you be peaceful and at ease.
As you say these phrases, again sink into their intention or heartfelt meaning. And, if any feelings of loving-kindness arise, connect the feelings with the phrases so that the feelings may become stronger as you repeat the words.
As you continue the meditation, you can bring to mind other friends, neighbors, acquaintances, strangers, animals, and finally people with whom you have difficulty. You can either use the same phrases, repeating them again and again, or make up phrases that better represent the loving-kindness you feel toward these beings. In addition to simple and perhaps personal and creative forms of metta practice, there is a classic and systematic approach to metta as an intensive meditation practice. Because the classic meditation is fairly elaborate, it is usually undertaken during periods of intensive metta practice on retreat.
Sometimes during loving-kindness meditation, seemingly opposite feelings such as anger, grief, or sadness may arise. Take these to be signs that your heart is softening, revealing what is held there.
You can either shift to mindfulness practice or you can—with whatever patience, acceptance, and kindness you can muster for such feelings—direct loving-kindness toward them. Above all, remember that there is no need to judge yourself for having these feelings.
