I've read the English original version of this book by the same author. The book is an exhaustive teaching on Advaita Vedanta. It starts from the basics to the most advanced concepts. It's a heavy read and has to be studied slowly. Re-reading parts read for the first time, the next day is recommended. Likewise making markings for relevant portions. If you follow these, rest assured the book is a treasure chest. It's you best reference on Advaitic concepts. Any doubts or questions you have on Advaita, you will find an answer in this book.
