Why is a detailed biography like the Shri Sai Satcharita considered more suitable for a 'Parayan' than other works mentioned?

As explained in Chapter 0, a detailed poetic biography is ideal for performing a Parayan or Saptah. The Shri Sai Satcharita is highlighted as a prime example of a comprehensive and famous work suitable for this purpose. The text contrasts this with other works, like those by Shri Dasganu Maharaj, where biographies of specific saints might only span two or three pages. Such brevity makes them not useful for a dedicated, deep Parayan. The detailed nature of the Satcharita allows devotees to immerse themselves in the Guru's life, which is considered a form of Guru service.
