Beginners will first meditate upon equanimity. Once that is established, they will then meditate upon the remaining three [immeasurable qualities of love, compassion, and joy]....

First, toward all those who are relatives, attachment is to be abandoned as though they were neutral. Then abandon aversion for enemies as though they were neutral and remain without partiality. In order to be free from delusion even toward the neutral, have the intention to dispel the passions of beings all at once. Meditate like this without clinging.
