This can be said to be the greatest of all Upanishads, not only in size but also in regard to the substance and theme it deals with. Shankarachaya's commentary on it is also the greatest of all his commentaries. The volume contains the text in Devanagari, a lucid and faithful translation of the text and commentary, relevant notes, references to quotations, and an index. All this makes this book indispensable to the students of Vedanta, especially those who are deficient in Sanskrit language, for a easy and correct comprehension of the subject.
There is only one sin. That is weakness.... The only saint is that soul that never weakens, faces everything, and determines to die game.
-Swami Vivekananda
