Why you are able to conduct a training programme on some book? You are able to do it because it has valuable contents. These contents when disseminated in organised manner will benefit section of the society. Nevertheless, while disseminating the contents, if you are earning money then this dissemination of contents becomes purely for commercial reasons.
Authors write the books to provide knowledge and information for students as well as professionals. Both can study the book to enhance their knowledge. Getting pecuniary benefits by implementing this knowledge is one thing and directly disseminating the contents to earn money is another. Therefore, it is violation of copy writes.
Writing book is not that easy. To write a book, authors invest their time and money in doing some research. While they do earn the money when each unit is sold out, nevertheless, their zeal of research or zeal to uncover the hidden truth of the nature is another. Let us respect their passion.
Copy write laws are not that strict in India. Otherwise, for plagiarism or piracy, the punishment is stricter in western countries. I recommend you obtaining official permission to conduct a programme. If you know a agency that conducts the training programme on this book then it is better to obtain the official permission by paying requisite fee.
Dinesh Divekar has given you sound advice with reasons explained. As a university lecturer, I have used material from various authors and training resources. No doubt I earned money doing my profession. When in doubt, it's is always prudent to write to the author or the publisher and seek their permission, explaining how you use their material. For example, I wrote a few chapters for Managing Total Quality book written by Dr. Hubert Rampersad. For that, I borrowed quite a bit of graphs and displays from various sources. I wrote to the publishers and they granted permission without any problem.
As you are declaring the source, you are not committing plagiarism; you are really giving free advertisement. Hence, as Dinesh Divekar has suggested please get their permission to avoid committing copyright violation.
