Could you describe the deepest sense of connection you have experienced?

Whether it is with another person, or a sense of connection with something larger than yourself, or a connection with the all, or a connection with yourself or a connection with something else, what happened that lead up to the experience and what did the experience feel like?

I’m more interested in the process leading up to the experience than I am in descriptions of the feeling of the experience. This is because the experiences themselves usually happen in a space beyond words, and it is very difficult to find words to describe them. Most people resort to cliches. But if you can do a good job of conveying the experience, go ahead; otherwise please describe the process leading to the experience.
