Can you explain the familial connection between the author Shri Saraswati Gangadhar and the Sadguru Shri Narsimha Saraswati Maharaj?

Based on the information provided in Chapter 0, the connection is one of ancestral lineage and a divine boon. Shri Saraswati Gangadhar belongs to the Sakhare family. An ancestor of his, Shri Sayandev, was graced by the Sadguru Shri Narsimha Saraswati Maharaj. Shri Sayandev received a special boon that his descendants would be destined to perform constant service to the Sadguru. The text clarifies that Shri Saraswati Gangadhar is the fifth descendant in this lineage starting from Shri Sayandev, thus fulfilling this ancestral duty through his biographical work.
