QUESTION: I got this lesson this morning. Give me your scholarly opinion if you will. Thank you. I thought it a bit perplexing.
Think on This ...
Study to know thyself in relationship to that ye choose as thy ideal. And let that ideal be set in Him, who is the way, the truth and the light. This does not mean becoming good-goody, no--far from it! Be able to look everyman in the face and tell him to go to hell--but live as He did, the lowly Nazarene!
Edgar Cayce Reading 2869-1
ANSWER FROM KEMP WARD: My feeling is that this passage is telling us to simply be who we are. And, it's saying to listen to our inner guidance and follow it. Unless we follow our inner guidance, we really can't be who we truly are.
And, it's telling us to give up judgement---of others AND ourselves. Do and say whatever we feel like, BUT do it without judgement. That way, you can have whatever interaction with others that you want to have, without anger or any other negative emotion. You aren't judging. When we judge or feel attack, we usually end up being a mirror of other people instead of who we really are.
Others may expect anger, but it won't be there if we refuse to judge or feel attacked. 
I tell my clients over and over to negotiate hard and push for what they want, but to NEVER EVER get mad or show any signs of irritation. I've made them memorize my favorite charge to them: "The first one to get mad loses."
