An inspiring mantra chanting with David Ma & Friends. They chanted a kirtan "Govinda Hare" during a satsang at Yoga Vidya Bad Meinberg, Germany. The first part of kirtan is:
Govinda Hare Om Hare Hare
Gopala Hare Om Hare Hare
The text for Kirtan can not be found in the Yoga Vidya Kirtanheft - if you want to know about mantra chanting, meditation, yoga and ayurveda, you'll find it on the website - just use the Google site search and Google website translator - of Yoga Vidya.
