Do you believe in the power of prayer? What do you think it can do?

I believe in the power of goodwill. It's all about harnessing the positive energies and utilizing those to benefit us and others. After all, we are just result of matter and energies interacting. Good or bad happens based on how they interact. Maybe through prayers, goodwill, meditation and other means we try to bring the best out of everything. For some of us it works, while it doesn't work for others. Maybe it depends on how devoted and focussed we are while performing any of those rituals, or maybe there's some process to do it right not known to us, but some just get it done without even knowing it.
