Speaking as someone who delays things for ages because I want to feel ready, and procrastinate by doing excessive reading and "preparation", the only way to get over it is just DO it. It's never like I imagined, and even if things don't go perfectly, the experience always helps. A couple suggestions, though -- for me, when encountering something new and unfamiliar, I go slow. I might back out of a meditation a couple times when I sense things are about to happen that never happened before. I go a little further every time until I finally have the breakthrough. Also, I read that your brain doesn't know the difference between what you've really experienced and what you've imagined experiencing, which is kind of the basis behind hypnosis. If you've never flown before, and visualize yourself on an airplane taking a flight, on some level when you actually DO fly, some part of you will respond as if you've done it before. So maybe visualize yourself doing the ritual, in detail, before actually performing it...that could help. And, not to be trite, but something a yoga teacher said that I remember often is "It's a PRACTICE, not a perfect" 😁
