The Four Brahma Viharas:

(The Four Noble Abodes , or Divine Abodes, often translated as ‘The Four Immeasurables").

1.      Loving-kindness (Pāli: mettā, Sanskrit: maitrī) towards all: the hope that a person will be well; "the wish that all sentient beings, without any exception, be happy."

2.      Compassion (Pāli and Sanskrit: karuṇā): the hope that a person's sufferings will diminish; "the wish for all sentient beings to be free from suffering."

3.      Empathetic joy (Pāli and Sanskrit: mudita): joy in the accomplishments of a person—oneself or another; sympathetic joy; "the wholesome attitude of rejoicing in the happiness and virtues of all sentient beings."

4.      Equanimity (Pāli: upekkhā, Sanskrit: upekṣā): learning to accept loss and gain, good-repute and ill-repute, praise and censure, sorrow and happiness (Attha Loka Dhamma), all with detachment, equally, for oneself and for others. Equanimity is "not to distinguish between friend, enemy or stranger, but regard every sentient being as equal. It is a clear-minded tranquil state of mind—not being overpowered by delusions, mental dullness or agitation."
