In the booklet, it is said that the noting should happen at the same time as the object, the mental note "rising" should begin at the beginning of the rising and end at the end of the rising, ie. should last the entirety of the rising.
I find that difficult because in my experience I can't do the mental note and at the same time be aware of the object. In other words when I do the mental note I'm aware of the mental note, and when that stops I can be aware of the actual rising. Is that normal? Is the appropriate thing to know the rising and then do the mental note? (in some of the Q&A, Yuttadhammo says that the noting happens after the moment of mindfulness of the object)
The mind can't be at two different places at the same time, so it seems impossible to have the noting and the awareness of object at the same time. At best it could maybe be a fast back and forth between them.
Hope my question is clear.
