Dear fellows, I think, we all can contribute to this teaching, as far as I'm your friend, not a teacher. So I will be happy to recieve any feedback.
Our Inner Compass... Some of our intenions and thoughts bring the feeling of genuine joy and inspiration. At the same time our mind tries to resist it or scare us. But in my opinion, if intention brings us these nice feelings, it means that our inner compass says - RIGHT DIRECTION.
In another case, thoughts provoke fear and hopelesness. Although mind gives us good mark like - it's absolutely right, rational and usefull initiative! But we can't hide these underlying fear and desperation. This time inner compass says - STOP WRONG DIRECTION.
But is it possible, that some  evil or irresponsible thoughts, like - go to bar and have a drink all night long again - will provoke in us the same postive feelings? In my opinion, it's impossible, if you really stop and listen to yourself.
