Stand as your handle
Your handle goes in the address — the figure draws your own place in it: you, the people you hold a channel with and theirs, and who met you in your room lately; and the channels you hold open for writing. Nothing is stored here but the path. Leave it empty, or choose nobody, to see the whole brain centred on no one.
