The success and achievement of an educational institution depends largely on the teacher and students. The relationship between teacher and student is most significant element affecting the quality of education and the institution. India always had a well-developed educational system which was intrinsic to the society. Gurukuls were spread across length and breadth of the country. The education was holistic and collaborative. The students lived with the teacher and his family, they learned by observation and example. Perhaps nowhere else in the world teacher were given so much importance. No person on the earth deserves greater reverence than the teacher, not even the father or mother. Teachers (Gurus) were considered more revered than the Gods.
It was the function of the teacher to lead the scholar from the darkness of ignorance to the light of knowledge. His importance therefore cannot be exaggerated; he is indispensable.
Since the earliest times, the Vedic learning is being transmitted orally in India form one generation to another. This continued to be the case even when the art of writing came to be well known. Great importance was attached to the proper accent and pronunciation in the Vedic recitation, and these could be properly learnt only form the lips of a properly qualified teacher.
With the rise of system of philosophy in the age of Upnishads, the reverence for the Guru became still more intensified; for spiritual salvation depended almost entirely upon his proper guidance.
