Does writing the biography of a famous politician count as a spiritual act that leads to salvation?

According to the Preface (Chapter 0), writing the biographies of worldly Gurus, which can include "unique politicians," is indeed considered a form of Guru service. However, the text explicitly qualifies this service as being "of a worldly nature." It emphasizes that while this work may involve public education, it is limited by space and time, its importance is not eternal, and it ultimately "does not yield spiritual fruits." Therefore, it is considered a one-sided or partial service that makes it difficult, if not impossible, to attain the ultimate spiritual goal through it alone.
