Many thanks for the very helpful comments/advice and information.
As stated in the following:
"There are, monk, these six quietenings. In him who has attained the first absorption, speech (vitaka) is quietened. Having attained the second absorption, thought-conception and discursive thinking (vicara) are quietened. Having attained the third absorption, rapture is quietened. Having attained the fourth absorption, inhalation and exhalation is quietened. Having attained the cessation of perception and feeling, perception and feeling are quietened. In a taint-free monk greed is quietened, hatred is quietened, delusion is quietened." -- SN 36.11
I'm wondering if all distractive thoughts are quietened in one who has attained the 1st absorption -- no pumping up of any undirected thoughts at all from entering such absorption to withdrawing? Or probably such a quietening is only for certain periods of time and then get lost and then get back ...? Does vitaka mean "speech" like "in/out" or "Buddho"? Is the mere following of the breath without such "speech" also a type of vitaka? Vicara seems to mean "directed thoughts" to me. Is the mere following of the breath without such "directed thoughts" also a type of vicara? It's strange I experience piti and occasionally sukha sometime before but not recently. To my understanding, the stop of inhalation and exhalation (when the breathing is done via the pores of the body instead of noticable breathing) is different from step 4 of the anapanasati, which means more like calmed, subtle breathing instead of non-detectable breathing. In Meditation4, such "still breath" (stop of noticable breathing) is considered as the mark of the 4th (sutta) jhana. Would it be possible for some people to experience such still breath before reaching any sutta jhana, while still feeling the body and hearing some sounds? Would one who has reached the 4th (sutta) jhana still hear sounds and feel the body at all?
Your kind help has been most appreciated. Metta,
