Geshe Ngawang Samten on secular ethics. In the west, ethics primarily refers to behavior. But in Buddhism, there is ethics of body (behavior), ethics of speech (your communication of information with others), and ethics of mind, based on as I mentioned earlier, the consequences generated by the thoughts and beliefs one holds.

Seems like mind ethics is most important, next slide:
Buddhist approaches to the modes of encountering affliction emotions (Klesha)
-Avoiding the object (at an initial stage, not always)
-Application of regulation of emotions through training and practice (antidotes?)
-Subjugation through non-transcendental path: training of mental stability through concentration
-elimination by the transcendental path: by perception of ultimate reality, affliction emotions (kleshas) are eliminated.

HHDL suggests that secular ethics go up through the second level here. I think it could also include the third.
