Yes. The book is too difficult to understand and needs good concentration and command over English language . I attempted to read it over and over again . It has helped to get answers to spiritual questions that I had. recommended for reading striving for gaining spiritual experience.
Well this book is very nice and it displays the extraordinary level of intelligence the indian sages had at that time...its very difficult to comprehend. It took me 4-5 readings of each page to understand everything properly. A must read if you are into spirituality and god. I was against reading religious books a year ago but after reading autobiography of a yogi i got hooked on to spiritual thinking.
The description says box-case, infact its a poor quality slip case. the packaging is extremely poor and i received it in a almost crushed condition. And you will get the same product from others in a better price.
