Can one attain the ultimate spiritual goal simply by writing biographies of worldly figures or even multiple saints? What is the recommended path for salvation through writing?

No, according to the source, one cannot easily attain the ultimate spiritual goal through these methods alone. Chapter 0 explains that writing biographies of worldly Gurus, while a form of service, does not yield spiritual fruits because it is limited and rooted in self-interest. Even writing the biographies of many saints is described as a partial path, making it "difficult, or rather impossible, to attain the ultimate spiritual goal" merely through that activity. The preface recommends a more focused path for salvation: writing the biography of one's own Sadguru and then personally studying it, performing hundreds of readings (Parayans), and conducting weekly recitations (Saptahs) with unwavering devotion and a pure heart.
