The text mentions that even a wise person can be deluded. How does one overcome this ignorance and doubt?

Chapter 50 explains that ignorance often manifests from doubt (vikalpa), which can make even a knowledgeable person prideful and deluded. The text states emphatically that this ignorance cannot be removed without a Guru. To achieve true knowledge, one must first understand and remove ignorance to purify the mind, which will then allow infinite knowledge to manifest. Furthermore, the text cautions that as long as a person is without devotion and their mind is fixed on wealth, luxury, and family, their supposed knowledge is actually covered by ignorance.
