I have read the malayalam translation of this book titled" hridayathinde sahasikatha". It contains chapters which has the speeches by Chariji in presence of his guru Babuji which where held outside India. It speaks about Rajayoga or sahaj Marg now known as Heartfullness meditation. In each chapter Chariji explains various concepts of meditation. It will be a good book for those who practice hertfulness meditation and wish to gain indepth knowledge in meditation and spirituality. This knowledge inspires you to practice meditation and gives motivation. It is advisable to read "the heartfulness way" before reading this book to understand the basic concepts.
Great and incredible articulation!! As we say, "Light is valued for revealing things as they are." These series of books are really like 'lighthouse' for those who are on the journey of self-knowledge. A complete set of wealth of insight & wisdom.
