The Preface mentions 'unique politicians' and 'extraordinary jurists' as worldly Gurus. Can you give me the list of specific individuals that Balkrishna Vishwanath Dev approved of?

In Chapter 0, author Balkrishna Vishwanath Dev mentions categories of people like 'unique politicians, state-founding brave warriors, extraordinary jurists, historians' as examples of 'worldly Gurus.' The purpose of this mention is to draw a distinction between service to them, which is worldly and yields temporary fruit, and service to a Sadguru, which yields spiritual fruit. The text does not provide a specific list or name any individual politicians or jurists. These titles are used as general examples to illustrate a philosophical point about different types of service, rather than to endorse any particular figures.
