Negative emotions

Dear Brooke,
I am reading now the Law of Attraction by Abraham Hicks. He writes that negative emotions are felt when we create inadequately and therefore they indicate when we are not in harmony with our inner being. So, we should stop what we’re doing and focus all of our thoughts on something more positive. (I read it in French so I hope the way I translate is coherent)
Here, you are explaining that it is essential to feel and experience negative emotions, that we should accept what we are given.
How can I reconciliate these 2 teachings? Specifically knowing that Abraham is important to you and that you definitely have the answer I couldn’t have figured out yet 😉
Thank you a lot
Très belle journée 🙂
