Effort is made to overcome fear through discovering its causes. Why do you want to discover the cause? Is it not because you do not want to suffer, you are afraid to suffer? So you hope that, through fear yielding to fear, all fear will be overcome. This is an impossibility.
Now do you make an effort to discover the cause of joy? If you do, then joy ceases to be and only its memories and habits exist.
