When you are trying to influence your own body (f.i. calmness, breathing, heartbeat-throug breathing) by mind it can be helpful to use an instanced person to do so. It is important that this instanced person does not have any more attributes then a first name and dedicated tast. (For me it’s Joe/John (Doe)) just pick the first name that come to mind.
Assign this person, which of course is a part of you, with the task you would like to acchieve atm. (lets say control breathing). By commenting and helping Joe by „talking“ to him, helping him do his task, assuring and complimenting him can help a lot.
[extend -> manipulate wishes of higher/lower volitions via instanced persons? -> can help find out answers what „it’s“ about]
