The present edition of Bharatatattva is in more than one sense and effort at a purposive revision- both in content and in form- of an earlier text of the same title.
The important thing is how much less you think of the body, of yourself as matter -- as dead, dull, insentient matter; how much more you think of yourself as shining immortal being. The more you think of yourself as spirit, the more eager you will be to be absolutely free from matter, body and senses. This is the intense desire to be free.
-Swami Vivekananda
