Whether you believe in God or not does not matter so much, whether you believe in Buddha or not does not matter so much; as a Buddhist, whether you believe in reincarnation or not does not matter so much. You must lead a good life. And a good life does not mean just good food, good clothes, good shelter. These are not sufficient. 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 rights and human dignity.
