According to Chapter 17, what are the main obstacles a person faces when trying to pursue the path of Shreya, or true self-interest?

Chapter 17 details several significant obstacles on the path of Shreya. The primary one is the allure of Preya, the path of worldly pleasure, which is fueled by an obsession with things like gold and women, and a craving for worldly objects. The chapter also identifies beginningless ignorance, or Maya, as a great obstacle, comparing it to a mirage or false imposition that must be dissolved. Furthermore, as stated in this chapter, desires for seen and unseen enjoyments, hope, and cravings are hindrances that must be dug out by the roots. Finally, the text points to lust and anger as tendencies that disrupt the attainment of knowledge by interfering with listening, contemplation, and meditation.
