It's not easy for me to express this idea, but with the help of the Holy Spirit, it's not only possible but also easy.
We hear these terms daily; however, let's clarify them a bit using A Course in Miracles to see that there's a tremendous mix of words that don't represent what they really mean. To a certain extent, it's impossible for this to happen.
"Mood" is a phrase that makes no sense whatsoever. Let me explain why. "Mood" comes from "soul" or "spirit." The spirit is always the same; being a creation of God, it doesn't change. A couple of days ago, I heard someone talking (according to her, a medium) about the evolution of the spirit. It's clear she doesn't know what she's talking about. The spirit cannot and should not evolve, since it is a creation of God. What does evolve is the mind, which actually unlearns in order to learn what is right and not what it learned that was wrong. Some also talk about new and old souls. This in itself is a mistake, although it doesn't change anything at all. There are no new and old souls. Creation was one and still is. There is no time, therefore no age, in God's Creation, which is the only creation that exists. Everything else is the making of the Son of God. (In this case, "son" is written with a lowercase "s," while if we are speaking of Christ, it is capitalized, since He is the Son of God in Creation.)
Feelings come from feeling, and we feel with our senses. However, emotion is mental, and the mind transmits it to the body, which reacts according to that transmitted emotion.
The basic concept is: emotions generate a state of being in that moment; many identical emotions, repeated, form a state of being.
The remedy, as always, is Atonement, to change those emotions and, consequently, the state of being and the state of existence.
