At present, our experience of the mind has the shortcomings and defects of habitual conditionings. At the same time, our mind has the potential to become completely free of defects and limitations. The difference between the defects and the potential is great; the defects are entirely extraneous to the mind, while the potential is inherent. Therefore, no matter how serious our present limitations may be, we can work with our minds and achieve a state completely free of such limitations.

-- Khenpo Karthar Rinpoche
