Hi Derek,
Good post.
A sound and solid piece on Breathing meditation is always welcome. My humble point of view.
I liked your: 'let...go' approach.
The listed info links. The insight timer people for some reason seem to have often occurring glitches: A slowness for the app to kick in, an often confusing steps to reset timers and bells, seems often times too overloaded with 'stuff'. I still use Insight... I suppose there may now be others out there but I have faith that Insight will rectify...
Of concern lately is an over focus on the putting on an altar ones times and frequencies. The teachings of course recommend not to dwell on my 'record'. Oh well, no big deal really but might be helpful.
Keep up the good work Derek.
Tom
