Although we need to be acutely aware of our faults we must never allow ourself to become overwhelmed or discouraged by them. We may have a lot of anger in our mind but this does not mean that we are an inherently angry person. No matter how many delusions we have or how strong they are, they are not an essential part of our mind. They are defilement a that temporarily pollute our mind but do not sully it's pure, essential nature. They are like mud that dirties water but never becomes an intrinsic part of it. Just as mud can always be removed to reveal the pure, clear water, so delusions can be removed to reveal the natural purity and clarity of our mind.
