Zen Buddhism bridges the gap between religion and science.
Buddhists strive to obtain the end to the cycle of continual reincarnation that produces endless existence. Like a drop of water returning to the ocean, obtaining Nirvana allows one to directly perceive reality and produces an awakening that connects the Buddhist to all things in the universe. Buddhism like all religions is a closed system of beliefs.
Zen Buddhism is more like science, a philosophy of research and experimentation into possibilities toward a more enlightened existence. Religion is based on tradition and faith. Science is based on doubt, proof, and future concepts. The difference between philosophy and religion is that philosophy is questioning and religion is answering.
