It is during these stressful times when a devotee can make progress and jump over obstacles that Maya puts in front of him/her. When a devotee directs his attention towards Krishna during those moments of utter helplessness and despair, those moments can be the most rewarding. Krishna is there watching. He is there in your heart and He knows when you see no one other than Him to turn to.
