How can studying a Guru's biography help someone who is facing distress or worldly problems?

The source explains that texts like Guru biographies can be used in two ways. One way, known as Kamya, is specifically for worldly purposes, such as achieving prosperity or seeking the removal of worries, calamities, distress, and diseases. As described in chapter 0, a Guru's biography, which is a reliable book detailing the Guru's life, miracles, and works, can be studied with this desire-driven intent. While the text also notes that selfless (Nishkam) study for liberation is considered superior, it clearly acknowledges the ancient practice of using these texts to address worldly concerns.
