How does one achieve true knowledge and transcend ignorance according to these teachings?

The path to enlightenment involves a nuanced relationship with knowledge and ignorance. Chapter 8 explains that both knowledge and ignorance are modifications born of nescience (avidya). The process is compared to using a thorn to remove another thorn. First, you must use knowledge to remove the 'soot' of ignorance and the 'oil' of worldly desires. However, the ultimate goal is to then transcend both knowledge and ignorance, throwing both away to remain in the pure, unadulterated state of one's own nature. This is described as the one true goal of human birth.
