Acharya Ekkirala Bharadwaja, lovingly called by his disciples and followers as "Sai Master", is one of the greatest scholars and philosophers of the modern times. He researched the Spiritual science as well as the Physical science of the modern age in the quest for the purpose of all life in the world. Surprisingly, he understood that both of them are not exclusive of each other, rather they guide towards the same goal----the existence of 'Viswa Chaitanya' or the "Universal Consciousness", the oneness in all duality, i.e., The 'God ', in spiritual terms.
