The butterfly for hospice care givers; represents the transformation of the spirit as it reaches the end of its cycle of living, and becomes free to take flight in a spiritual world.  As a person passes away, they do let go of all of the burdens here on earth; pain, suffering, feelings of helplessness, and of course, fear.  If you believe in heaven, or that there is a spirituality that takes the place of the body, after death, then the butterfly is the symbol of that kind of boundless freedom that you can expect to feel, when you reach that point in your existence, the point when your earthly existence ends. "Butterflies are free".
