How does the text connect the act of writing a Guru's biography to ancient spiritual practices and the ultimate goal of salvation?

The text in Chapter 0 synthesizes multiple concepts to link writing a Guru's biography with salvation. It posits that the most effective service is writing the life of one's Sadguru. This act is then connected to the ancient Vedic-era practices of Parayans and Saptahs (repeated devotional readings), which are also performed for revered texts like the Vedas and Ramayana. According to Chapter 0, when this service—whether writing or reciting—is performed with a selfless mind (Nishkam) rather than for worldly gain (Kamya), it becomes the highest and most incomparable form of Guru service, ultimately granting liberation from the cycle of birth and death.
