It is a myth that crying over a loss continues forever and impedes our progress. Converse is true. Not crying over losses and deaths creates a 'burden' in the body that we are not consciously aware of. This burden is only experienced when it is allowed to let go. As long as one is holding on to the burden, one does not realise that it is being carried. We are so used to carry it anyway.
Our nervous system goes into stress mode when our body perceives any threat. At that time the process of crying is suspended. It is only when a person starts to relax that the crying activity occurs. Physiologically, the parasympathetic nervous system is responsible for relaxation. Crying or shedding tears, is a parasympathetic activity too. So people who are stressed out do not cry. But they are not happy either.
When someone cries over a loss, it means the nervous system is getting 'comfortable' or is reaching a stage of 'accepting' the loss. This causes a balance between the sympathetic (stress producing) and the parasympathetic (relaxation producing) parts of the nervous system. The crying that involves grief almost ALWAYS ends.
