Yoga Yagna is a 21 day Yogathon where people practice yoga at home or in the yoga class and report it to the group on their practice. This serves as a motivation for others to practice in a community setting. Yoga Bharati conducts Yogathon in Winter and summer to bring awareness about the benefits of yoga in the community.
