This is the difference between negative and positive emotions: if you become aware of a certain emotion, and by your becoming aware the emotion dissolves, it is negative. If by your becoming aware of a certain emotion you then become the emotion, if the emotion then spreads and becomes your being, it is positive. Awareness works differently in both cases. If it is a poisonous emotion, you are relieved of it through awareness. If it is good, blissful, ecstatic, you become one with it. Awareness deepens it.
Use your awareness. It is just as if there is darkness and you bring in light: the darkness will be no more there.
