“ After my recounted experience, it would be extremely tempting to pursue religiosity, but I realise that the experience was a one-off. It isn't the path (albeit comforting) I must walk on . The path is to dig deep within and find my own source of internal comfort, or is that just another form of serenity?”
don’t know about the serenity bit, but i wonder why you would mot explore more about the experience you DID have; it sounds like the “one-off” is leading you to box it up instead of opening it into the “rest of life”.
doesn’t it tell you something about what is possible, what might be “more”, without having to be put into a “religiosity” category?
something wonderful happened to you.
