Explain the difference between studying a Guru's biography with a 'Kamya' versus a 'Nishkam' intention, and identify which approach is considered superior.

According to the source, studying a Guru's biography can be done in two ways. The 'Kamya' approach is undertaken with desire, specifically for worldly gains such as prosperity or the removal of worries, calamities, and diseases. In contrast, the 'Nishkam' approach is performed with a selfless mind, aiming for spiritual liberation from the world and the cycle of birth and death. As clearly stated in Chapter 0, the 'Nishkam' form of Guru service, whether through studying texts or any other method, is always considered to be the superior path.
