Nrtta Sadhana Demo by Shadow Yoga Teachers Watch this beautiful video by our international community of Shadow Yoga teachers demonstrating the rhythmic life currents of Nrtta Sadhana. Nrtta refers to ‘pure’ dance. It is that Sadhana by which the sadhaka rediscovers the rhythmic life currents hidden within the body through unimposed natural positioning. The eighth sutra of the Pashupata Sutras lists Nrtta as a method of worship and this is achieved by combining a number of short movements termed karanas. 108 of these are described in the traditional scriptures but only a few of those most suitable for internal cultivation are required in this sadhana.
