The goal of life is to make your heartbeat match the beat of the universe, to match your nature with Nature.

Campbell frames a fulfilled life as one lived in attunement—where personal desire, conduct, and inner rhythm align with the larger patterns of existence. “Heartbeat” suggests the intimate, bodily sense of being alive; “the beat of the universe” points to an encompassing order (nature, mythic law, or spiritual reality) that exceeds the individual. To “match your nature with Nature” implies discovering one’s authentic disposition and letting it harmonize with the world rather than fighting it through ego, anxiety, or social imitation. The line echoes Campbell’s recurring theme that myth and spiritual practice aim to reconcile the individual with the cosmos, turning life into a participatory, meaningful experience rather than a merely private struggle.
