Once renunciation and the awakened mind have been fully realized, the way to Buddhahood is clear. Liberation is complete and such liberated beings are then Bodhisattvas and Buddhas: "enlightened ones," or "empty dwellers." Their usefulness to others both before and after their physical death, is impossible to conceive. They are nothing but useful energy leading to liberation for all beings still caught in conditioned existence.
