Once the Eternal Buddha reveals his unborn and deathless true nature, Buddhahood is no longer just a theory, or the achievement of a special person who lived in the distant past, or a remote future possibility. Buddhahood is the essential truth of the present moment that the other teachings point toward. This is why the One Vehicle teaching of the historical Shakyamuni Buddha is considered to be the reflection of the Eternal Buddha in this world of impermanence, while the Eternal Buddha is the ever-present actuality that is the source of all such reflections. It is important that we receive this teaching with faith and rejoicing, and spread it to others.
