To get their attention, make a small sacred space in your home and yard, and lay three types of offerings:
-sweets
-rice-based alcohol (Makgeowli, Sake, etc)
-tea
Lay these about a central fire, clap thrice, and bow your head. Make an offering of goodwill from your heart, and wait for what feels like an acknowledgement. Leave the offering out for a day or two at most, then dispose of it according to your tradition.
-do not- consume the offering until given explicit permission to do so. Its not yours, and these are the spirits you're likely just getting to know.
If you do this and build goodwill, you will have more friends at your beck & call than before.
-Hannya, of T's system
