" The highest perfection of altruism, the ultimate altruism, is bodhicitta complemented by wisdom. Bodhicitta—the aspiration to bring about the welfare of all sentient beings and to attain buddhahood for their sake—is really the distilled essence, the squeezed juice, of all the Buddha’s teachings, because ultimately, the Buddha’s intention is to lead all sentient beings to perfect enlightenment, complete omniscience. Since it is bodhicitta that determines whether or not our practice becomes the path to enlightenment, bodhicitta is truly the heart essence of all the teachings of the Buddha. "
