Lay Morality http://www.lankaweb.com/dhamma/view12.html
The Buddhist perspective of morality is given in a nutshell in the little Pali verse. "Sabba papassa akaranam - kusalassa upasampada sachitta pariyodapanam - etam buddhanu sasanam" "To keep away from all evil, cultivate good, and purify one's mind is the advice of all Buddhas."
Sila http://www.accesstoinsight.org/ptf/sila.html
Sila (virtue, moral conduct) is the cornerstone upon which the entire Noble Eightfold Path is built. The practice of sila is defined by the middle three factors of the Eightfold Path: Right Speech, Right Action, and Right Livelihood.
The Meaning of Sin and Evil http://www.dyad.org/d07sin.htm
"Buddhism has a completely satisfying answer to evil and sin. The Buddhist approach would be to question your "desire" to be without sin or evil, to look at the question itself. Why would you limit your life? To trap you into an experience that western language finds difficult to say directly. To direct your search to the real truth. Here our normal "logical" English language just breaks down. What is this "illogical" experience that is not linear and deductive? The answer is "There is - in fact - a life that can be experienced outside of the level of thinking." I call that the essential teaching of Buddhism."
