A bodhisattva is someone who has taken on the sole task of meeting the needs of others, no matter how difficult that might be. His self-centeredness has been reduced to the point where wisdom, love, and compassion arise naturally, benefiting any situation. Motivated only by concern for others, he would offer his own life without regrets if he saw it would be of help. So the mind of a bodhisattva is heroic, vast, and of limitless benefit.
