Thank you for reminding us of the Buddha's Teaching and for reminding us to try to do right things.

Perhaps,

๑. ละเว้นการทำความชั่ว ( Don't do evil deeds )

๒. ทำแต่ความดี ( Do only good deeds )

๓. ทำใจให้ผ่องใส ( Clear our mind )

would be more understandable in English.

Buddha's Teaching in plain and simple English can be accesses from <http://www.accesstoinsight.org> and many other webs linkable from there.
