Look at emotions ... what are they for. So far what is seen is that they are a way to experience the Self. Though the Self cannot be experienced, because to experience the Self one would have to be removed from it … that is Emotion … it is one step removed from the Self; yet the closest experience of the Self one can have in the body; since the body is very limiting.
Emotions are a cage on the Light/Self or a box on the Light/Self. The Light is only Love (not emotion). Love is not an emotion … Love IS. An emotion is happiness, or sadness, or anger or depression; that can all come up around Love, but are not Love, nothing can be Love, but Love itSelf.
