DRG-DRSYA-VIVEKA

"This small book(Drg drsya viveka) of forty-six slokas,is an
excellent vade mecum for the study of higher vedanta.Sixteen of the slokas
from Drg drsya viveka,from 13 to 31 with the exception of 14,21,and 28,are
found in a minor Upanishad,called the Saraswati-Rahasyopanishad.It does
not seem probable that the author of Drg drsya viveka wrote a treatise of
forty-six stanzas borrowing sixteen from another book.Neither of the two
commentators(Brahmananda Bharati and Ananda Jnana) has mentioned these
sixteen slokas as quotation from the Upanishad in question.Therefore it
seems to us that the author of the Upanishad has borrowed these slokas
from Drg drsya viveka,which,if true,would indicate the importance of the

book."
