Hello again Coolbreeze,There is certainly a place in meditation for what you are doing in seeing where thought arises and goes to. It is more easily achieved if you can first stabilise the mind through developing relaxed concentration. This also involves developing equanimity: non-judgemental awareness through allowing thoughts to be, but not labeling them as good/bad or negative/positive - just noticing your awareness has shifted from the breath to thoughts and gently returning it to breath repeatedly. Your mind will wander lots of the time when you begin so accept this as it is.Once you have an ability developed to sit and concentrate on the breath with an awake and stable mind you can turn these skills towards the arising and falling off thoughts without identifying with them or following them with more thoughts.Keep it up, it's called meditation practice for a reason Be well,Matthew
After thousands of attempts I learn how a thought arises and grabs my attention. And watch each thought arise and fall without grabbing it and let it become a thought trail of past or future.
I wouldn't worry about stages of Jhanas and all that carry-on. Just sit and practice, it you stop trying to get somewhere you'll arrive.
