Aparigraha, non-hoarding, is an important step in yoga. Even intellectual hoarding is a hoarding. A person who has gyan needs to give away that gyan. Out of all the things in the world, giving away knowledge is one of the noblest giving. That is the reason why in ancient times people who used to give away knowledge, Brahmins, used to be considered above all the others. The teachers had a major role to play in our society in ancient times. They used to be considered even above the kings. Where have we reached now? Why does teaching as a profession not give as much importance as it deserves? Why do the best minds of our times don’t go in teaching?
