What does attaining Buddhahood mean for us? It does not mean that one day we suddenly turn into a Buddha or become magically enlightened. In a sense, attaining Buddhahood means that we have securely entered the path, or orbit, of Buddhahood inherent in the cosmos. Rather than a final static destination at which we arrive and remain, achieving enlightenment means firmly establishing the faith needed to keep advancing along the path of absolute happiness limitlessly, without end.
