Question of Karmayoga of Swami Vivekananda

Question: Presently I am reading Karma Yoga – The Yoga Of Action by Vivekananda. As I read this book I found that my approach towards life, people and in fact towards me was not as what I must have been. I am really feel very sharp towards what I want to do and how should do it. I have few queries regarding to the book, they are as followed.

What Vivekananda had written was already written in Vedas and he had mold the knowledge of Vedas in to book or the concept of Karma Yoga was child of Vivekananda?

If I write a book about how to implement concept of Karma Yoga in business process, is there any copyright matter exist for the book?

I also want to know in which language originally Vivekananda written this book?

Answer: Swami Vivekananda himself has said that he has said nothing new other than what is already found in Vedanta. His contribution is – putting the matter in the modern language in a systematic way so that it can be well understood by the modern man. To put it in a proverbial language, “Old wine in a new bottle”. There is no copyright, but if you are reproducing the same, you have to take the permission from the publishers. Most of the works of Vivekananda are in English.
