More than 15,000 Volunteers of Patanjali Yogpeeth under the guidance of H.H. Swami Ramdevji Maharaj and Revered Acharya Balkrishnaji were engaged in the relief work for Bihar disaster affected persons. H.H. Swamiji Maharaj & Revered Acharyaji Maharaj went to the flood affected areas to help the affected people in dealing with the catastrophe.
