Question: Is it still the same great souls who do great things in so many different fields?

Sri Chinmoy: In one incarnation they are great in one field. In one aspect of life somebody may be great, and in another aspect he may be useless, useless, useless!

New great souls do come to earth, but they do not become great souls overnight. Nobody can be great or good overnight. Some started their journey in a particular field four hundred years ago, let us say, and then after some time they became great. Others started perhaps two hundred years ago, and then after a few human incarnations they also became great. The ones who became great later we can call new souls. Some became great many, many years ago. They worked hard and they became great. Others started later. It is a matter of when they started their preparation.
