What does it mean to purify one’s morality?

In this short excerpt from a talk given in Calgary, B.C., Canada, Doug Sensei discusses “the purification of virtue (sila)” as part of the traditional “seven stages of purification” and defines sila as being in a state of fundamental friendliness toward self and others. Sanskrit terms: sila: “coolness” or  “cool-headedness” kusala: skilful, virtuous http://www.quangduc.com/English/kusala.htm
