Who was the poet Shri Dasganu Maharaj, and why are his works considered less useful for a Parayan of a single saint?

Shri Dasganu Maharaj is identified in Chapter 0 as a poet who composed three Marathi works, including Shri Bhaktalilamrut and Shri Bhaktisaramrut. While these works can be used for a Parayan, the text explains their limitation for a specific purpose. If a devotee wishes to perform a Parayan or Saptah focusing on the biography of one particular saint, Shri Dasganu Maharaj's works are described as not being useful. This is because the biographies within them are not comprehensive or detailed, often taking up only two or three pages.
