All beings have the potential to become Buddhas, for all of our minds are innately pure. At the present, they are clouded by disturbing attitudes and negative emotions (klesa) and contaminated actions (karma). Through constant practice, we can remove these defilements from our mindstreams and nourish the seeds of the beautiful potentials we have. Thus each of us can become a Buddha when this process of purification and growth is completed.
