The mind (sometimes) likes that it is driven by the same driver as all other things. It somehow thinks this belief will make all other arisings in the future insignificant to it.
The key here is the mind never did know, it only knew of, so it can’t remember to be something it isn’t. The mind’s job is to think, it only appears to have a problem when it thinks it is you. People notice unthinkable things happening frequently which are caused by belief in things we are not. Safe to say there is no harm in telling people they are definitely not what they think.
We are the essence of moveable things , this is amazing to the mind and this knowledge will keep it from straying very far, but realize it should move as always. What you are can’t and shouldn’t change and all arising as you’ve noticed must change, it is that simple and complete.
