The main theme of Buddhism,” the Dalai Lama began, “is altruism based on compassion and love.” He then went on to teach the foundational Tibetan Buddhist practice of “mother recognition”: imagining all beings as one’s mother.
Again, in order to have a sense of closeness and dearness for others,
you must first train in a sense of their kindness through using as a
model a person in this lifetime who was very kind to yourself and
then extending this sense of gratitude to all beings. Since, in
general, in this life your mother was the closest and offered the most
help, the process of meditation begins with recognizing all other
sentient beings as like your mother.
