Is appropriate to mentally talk to myself during meditation? Let’s suppose the primary object of my meditation is breathing. I usually just notice the exact point where my breath touch my nostrils and in my mind without words I just acknowledge this finding without words. 

Now I wonder if, instead of just realizing it, I can also use words and short sentences in my mind like “the air touch there”.

I was reading about a vipassana technique call “noting”. If I understand it correctly when my mind drift to a secondary object I can just mentally talk to myself that I notice it and go back to the primary object. 

I am curious if the same could apply to the primary object. I mean if whenever I notice something about the primary object I can tell about it to myself with mental words.
Everything I've heard suggests that this is OK, though it's not ideal. Ideal meditation would be stillness without interruption of thoughts; handling words in the mind requires thought.

I recall an Audio Dharma podcast where it was suggested that if you must do this, try to keep the words as brief as possible "In breath." "Out breath." That sort of thing. :-)
