This book is a critical evaluation of practical experiences of the author in yoga with reference to modern science. 'Dibyajagat' in Sanskrit and Bengali means the divine world whilst 'Daibibhasha' in the same represents the language used in that divine world. By venturing into that world himself, the author gives a detailed account describing the way signs and symbols (the language of the world) come to a Yogi who follows the path of meditation indicated in the book itself. The meaning of those signs and symbols - how to decipher - are discussed at length.

According to the author, whosoever follows the path of this brand of meditation would be able to evoke and energise his/her fine body so that these symbols start coming one after another and the meanings there on are told from inside.
