Clearly it is important to let out our emotions; to find some means to express and release them. It was suggested that we allow ourself to feel whatever feeling comes toward us in the moment before us such that we submerge in that feeling. Once we connect with the feeling we ought to express it and thereby release it.
One method to give expression to feeling that I read online was through movement. So that we move spontaneously synchronized with feeling and it said doing this releases couped up emotions. Yoga too is an extremely powerful tool to enable emotional catharsis. As is writing poetry.
It is important to remember though that the goal of catharsis is a healthier self and therefore movement toward a stronger character. Therefore it should not lead to a compromise of (our) intent.
