".......Motilal Banarsidass Indian Edition Of Denssen's Book Is Quit Welcome....... For No Student Of Vedanta Can Hope TO Start His study In A Proper Manner Without Going Through Denssen's Work." (Journal Of Indian Council Of Philosophical Research, Vol.19, No.2, April-June, 2002) The philosophy of the Upanishads according to Paul Deussen is the culminating point of the Indian doctrine of the universe and this point he said had been already reached in Vedic pre-Buddhistic times and in philosophical significance has been surpassed by none of the later development of thought up to the present day.
The book would create a great interest in the study and research in Indology. ...the people interested in Upanishadic studies should read this book for getting better insights into the philosophy and philosophical history of Upanishads. - Godabarisha Mishra
