Christianity teaches us that the way to connect with life is by serving others. The last shall be first. The way to the holy is by way of service, of doing something for others, of losing oneself in relationship. The way to the mystery is often by way of the soup kitchen, or some simple act of kindness and caring. In as much as you have done it to one of the least of these, you have done it unto me.
Mystical feelings are universal among humans.
You can have them whether you are religious or not. Anthropologists say that they may be part of our survival mechanism. Without the ability to transcend our self-centeredness our species cannot survive.
