In Buddhism, when we hear about generating immeasurable love and compassion towards all beings, it literally means all beings without exception. It does not mean just my family, or my friends, or my people from my country, or even just human beings from my world.
It means expanding our love and compassion so that it becomes immeasurable, so that it embraces each and every sentient being throughout all of the planes of cyclic existence, no matter where they are, no matter what form that they have.
~ Chamtrul Rinpoche
