According to Chapter 17, what are the main obstacles that prevent someone from following the path of Shreya, and what is the recommended approach to overcome them?

Chapter 17 identifies several key obstacles to pursuing Shreya, the path of salvation. The primary hindrance is the allure of Preya, which manifests as an obsession with worldly objects, wealth, and status, as well as the cravings of the senses. The text also points to beginningless ignorance (Maya) as a great obstacle, which is as false as a mirage. Furthermore, lust and anger are specifically named as tendencies that disrupt listening, contemplation, and meditation. To overcome these, Chapter 17 advises that one must first clearly understand what Shreya is and then struggle for its sake by strengthening the intellect and digging out desires by the roots, demonstrating true human effort.
