Sounds useful - do you still practice samatha meditation? If not then what made you stop?
We basically have 2 kinds of meditation.
1) Concentrate on a thing for a while.
2) Watch sensations come and go while refraining from moving your attention in reaction to what you're watching.
I did the first for a few years. Then I did both for a few years. Now I only do the second.
Both deliver the calm but they do it differently. They also do some other stuff.
The second is trickier than the first.
This sounds like standard "mindfulness" meditation, to me.
However, when you learn vipassana from a religious lineage, the various teachers and monasteries have slightly different techniques and progressions of the practice from what we'd consider "standard mindfulness".
