Last week’s classes focused on the niyama of tapas—internal heat, passion, austerity. We moved through three beautiful yang sequences that generate plenty of heat. (These are available on Paul Grilley’s wonderful Yin Yoga DVD.) Then we experienced the austerity of long holds in the yin style. This practice is so fruitful for athletes; it requires strong mental focus and using the breath to remain centered in the face of intensity.
