As used in classes at the Ramamani Iyengar Memorial Yoga Institue in Pune. The headwrap is a basic tool used to quiet mental activity and equalize internal and external pressure on the brain. It is frequently recommended for use during asana practice in therapeutic sequences and during the practice of pranayama. A personal headwrap, or eye bandage, as it is called in India, is recommended for any hygenic concerns. Can also be used as a soft prop under the dorsal spine, in the upper thoracic, under the neck, under the ankle, between the ankle and hip with folded legs. A handy thing to have around.
