I can't tell you how indebted I am to you for releasing me from the custody of "the Ashtanga police" (aside from the fact that for most of my life I've been sort of a "goody-goody," always attached to doing things "right" and following rules). Since I returned to my classes last Sunday, I have been teaching my students that it's OK to touch their knees on the floor to curl their toes under from Upward Facing Dog into Downward Facing Dog; I've stopped trying to pull them deeper into asanas (although I will still gently guide their spines in the direction they should be going, coax closing shoulders to open, etc.), but rather now emphasize the movements and directions they need to move their bodies in order to get closer into the asana themselves; and instead of telling students who close their eyes to open them, I now actually tell them, at certain strategic times, to close their eyes, not to feel relaxed, but to be better able to breathe more consciously, focus on moola bandha, and feel the prana without any visual distractions. I always gave them options for doing the vinyasa between asanas and right and left sides, but instead of only giving them a Lolasana alternative, I also tell them it's ok to even just inhale up from the right side and exhale into the left side. I even have many of them going over to the wall, now, to work on Utthita Hasta Padangustasana.
I hope it's OK if I use your terminology of trying to "move more air in and out of the lungs." It seems to take the pressure off them to, as DS so "cleverly" says, "make an asana of themselves," and focus on breathing and prana. I also absolutely LOVE your phrasing, "What's important is invisible." I think the world would be a much more peaceful place if everyone kept this in mind....
I've never been to Nova Scotia but I would think it's beautiful. I know wherever you go you will "keep the prana flowing."
