For real: After I started playing shaku 12 months ago, I practice much less yoga, my shaku playing gives me lot of what I before got from yoga. My wife can even see it if I had a good shaku practice, saying that I look like after a long pranayama (yoga breathing practice). But a lot of shakupractice also makes arms, shoulders and neck need a regular yoga practice (and the same with carrying children), so the last months have been with an increase in yoga practice, and that feels very nice!
I agree. I think prana and honkyoku breathing is very similar, and produces similar results also. And yes, I remember the days of carrying the babies. My back was often thrown out due to resting the child on one hip and the yoga postures helped me regain proper alignment. _________________
