A good motivation is what is needed: compassion without dogmatism, without complicated philosophy; just understanding that others are human brothers and sisters and respecting their human rights and dignities. That we humans can help each other is one of our unique human capacities.
If you have fear of some pain or suffering, you should examine whether there is anything you can do about it. If you can, there is no need to worry about it; if you cannot do anything, then there is also no need to worry.
There comes a pause, for human strength will not endure to dance without cessation; and everyone must reach the point at length of absolute prostration.
There is no fear in love, but perfect love casteth out fear. Fear is a painful emotion that arises at the thought that we may be harmed or made to suffer. As long as we must trust for survival to our ability to out look or out maneuver the enemy, we have every good reason to be afraid. Fear is torment. To know that love is of God and to enter into the secret place leaning upon the arm of the Beloved, this and only this can cast out fear.
When you look at yourself from a universal standpoint, something inside always reminds or informs you that there are bigger and better things to worry about.
