By thinking about and meditating on the Four Immeasurables, we lessen our disturbing emotions and attitudes, and we begin to open the heart, benefiting ourselves and others.
Immeasurable Love is the wish for all beings to have both happiness and its causes.
Immeasurable Compassion is the wish for all beings to be free from suffering and its causes.
Immeasurable Joy is the wish for all beings to never be apart from happiness and for it to increase more and more.
Immeasurable Equanimity is the wish for all beings to be free from attachment and aversion, that keeps some close and others distant.
Chamtrul Rinpoche will also speak about how these four are the foundation of bodhicitta - the mind of enlightenment - the compassionate wish to attain the enlightened state of a Buddha for the benefit of all beings.
