I'm eating crow, folks.
You all have been shoving Vipassana down my throat.
So I decided to do it after concentrating my mind like you're supposed to.
I had a direct experience of impermanence, sensing a constant shifting in my body, emotions, and mind moment to moment.
It wasn't full realization of impermanence, but it was enough to sell me on Vipassana.
The Samatha/Vipassana war is over!
Vipassana wins! Vipassana wins!
