Hypothetical situation. Let’s say a person had contact with an entity that agreed to share some information on the condition that that person never share it with anyone else. Then after they did agree (having verified through divination or other means that the communication was valid) they were given information, rituals, practices of empowerment, etc. From what I gather this seems to be a somewhat common occurrence.
That person might consider creating a peronal magickal cipher language with which to write information like this down, to prevent others from seeing it, and thus fulfill agreements of these kinds.
Although I realize that the very nature of the discussion may preclude those who could share information from replying, I would like to hear how others might have handled this type of situation.
