In fact, the greatest area of his expertise was his ability to manage. It has to be seen in context what Prabhupada did. From a single individual with absolutely no resources, and just his words, he was able to build a worldwide society of people, a global society, long before what we are calling the Age of Globalization, which is right now. I mean, we couldn’t find videotapes or cassette tapes or even the old cassette cartridges anywhere else in the world besides America. We used to wait at the post office in Bombay to make a long distance call, if we were lucky. Forget about communication, forget about any of this, and Prabhupada had a worldwide organization built up in three or four years. How he managed this should be studied.
