We've all seen it in different types of media, magic seals as a way to seal off some specific thing, be it personal roads, parts of ourselves or someone else, souls, demons, etc. Very common in Japanese media, especially. Pretty symbols drawn in ink and voila, sealed off. I was wondering which real world magical practice comes closer to this? Sigils come to mind but I don't think they're quite it.

It brings the concept of crossing to my thoughts, but given a symbolic manifestation/concentration point, maybe. What do you think?
