Practicing the path and liberating beings from suffering is the action of the bodhisattvas. The Lotus Sutra introduces us to a number of great bodhisattvas, such as Sadaparibhuta (Never Disparaging), Bhaisajyaraja (Medicine King), Gadgadasvara (Wonderful Sound), Avalokiteshvara (Hearer of the Sounds of the World), and Samantabhadra (Universally Worthy). The action taken up by these bodhisattvas is to help living beings in the historical dimension recognize that they are manifestations from the ground of the ultimate. Without this kind of revelation we cannot see our true nature. Following the bodhisattva path, we recognize the ground of our being, our essential nature, in the ultimate dimension of no birth and no death. This is the realm of nirvana – complete liberation, freedom, peace, and joy.
